10 Things to Consider Before Hiring a Java Script Programmer


The development of web applications and software makes use of the widely known JavaScript, hence many companies require qualified JavaScript developers to create online platforms, mobile applications and desktop widgets. Despite the success of the language due to the increasing demand for web-based applications, the recruitment of skilled JavaScript developers has remained a challenging task.

It can be quite challenging to find the perfect JavaScript developer for your project, considering the variety of developers available in the market. A comprehensive search and evaluation is important to ensure that you make the right choice. To assist you in making the best decision, this blog post offers 10 useful tips for what to focus on and what to avoid when hiring JavaScript developers. Let’s get started.

Where is a JavaScript Programmer Needed?

Before commencing the recruitment process for a JavaScript Developer, it is crucial to determine the purpose of the role. With its versatility, JavaScript and its frameworks can be utilized to create diverse technological applications such as mobile and web apps, interactive websites, web servers, and games. This is one reason why it remains so highly in demand.

It’s worth keeping in mind that not all JavaScript developers have the ability to design and develop new technologies from scratch. Moreover, not every programmer can effectively use JavaScript when developing new technologies. Different developers have their unique skills and capabilities, and therefore it’s crucial to assess your specific requirements before selecting a team of JavaScript developers.

Before initiating your search for JavaScript developers, it is advisable to ponder over factors such as project requirements, associated frameworks and technologies, desired functionalities, project progress, and team size that is necessary to accomplish the project objectives.

A general norm is to categorize JavaScript developers into one of three main specializations:

1. JavaScript Developer

The responsibility of a Front-end Developer is to create the user interface of a website or web application using commonly used technologies such as CSS, HTML, and JavaScript.

JavaScript has substantially contributed to creating a dynamic user interface and enhancing website performance. It is common for companies to hire JavaScript developers to create an engaging user experience that motivates visitors to stay on their website for longer, thus reducing the chances of them leaving.

JavaScript employs interactive elements like menus, image sliders, tabs, and pop-up menus to improve the user experience. Each element of a website or application is defined by its functionality and visual appearance, collectively known as the User Interface (UI). The next time you browse the internet, take note of the many dynamic parts, as the frontend JavaScript developer is typically responsible for designing the elements you see.

In order to construct the interface, design the layout, and enhance the user experience of a website, it is advisable to hire JavaScript programmers, especially for front-end development.

2. JavaScript Developer/Designer

The widespread use of web development today mandates the use of JavaScript in the backend. When developing a web application from scratch, it is essential to ensure that all its components can communicate seamlessly with each other. It is imperative for the backend to support the frontend to optimize the overall functionality of the program. To achieve this, a programming language that enables communication between these two components is required. This is why businesses often hire JavaScript developers to create the backbone of the system.

JavaScript simplifies the process for programmers to troubleshoot, implement new features, and manipulate data. Nonetheless, the primary responsibility of a Back-end JavaScript Developer is to develop the foundation of the application and its database. Their key duty is to maintain the backend servers of a website. Backend development process commonly relies on JavaScript frameworks such as Node.JS and Next.JS.

To maximize productivity, it is recommended to team up frontend developers with a backend JavaScript developer. It is advisable to recruit JavaScript developers who possess a strong command of Node.js, have expertise in API development, and adept at integrating backend systems with the user interface.

3. JavaScript Full-Stack Developer

Full-stack engineers refer to industry experts who have proficient knowledge in front-end and back-end development using JavaScript. They are accountable for developing both the client and server-side of an application, designing user interfaces, implementing databases, and the actual app. Recruitment of full-stack JavaScript developers is an excellent approach to assuring that all aspects of a project are addressed.

Full-stack engineers have a comprehensive understanding of all aspects of a project, making them an ideal choice for management positions. However, if you need help with a single task, they may not be the best option as they lack a complete grasp of the entire program. In such cases, you may be better off hiring full-stack JavaScript developers to build a new application or assist throughout the development process. You can find dedicated JavaScript developers by exploring the market and selecting the right fit for your project.

Approaches to Employ or Avoid When Recruiting JavaScript Programmers

1. Hire a JavaScript Developer who Possesses Excellent Communication Skills.

Effective communication is vital in every profession. Particularly in the IT industry, where new issues and challenges emerge daily and must be communicated to both the team and the customer in a concise manner. Efficient communication between team members can prevent any possible misunderstandings or errors in the workplace.

Given the complexity of JavaScript, it is crucial to find software engineers who can communicate effectively with clients. The developer should be able to articulate themselves clearly using plain English to clarify queries, propose ideas, discuss concepts, specify requirements, address any challenges, and offer potential solutions relevant to the project.

2. Hire an Expert JavaScript Programmer

Life-on-life training is an experiential process that cannot be taught but must be learned over time. This is true for those who work with JavaScript as well. Although any developer can be employed for a project, it is recommended to search for professionals with expertise in JavaScript for optimal results, even if their rates may vary due to experience.

If you’re contemplating recruiting JavaScript programmers, you can be confident that your project will be managed expertly, meeting and even exceeding all your requirements, thanks to the developer’s ability to understand the market’s needs and develop applications accordingly. However, they often command higher compensation than typical software engineers. Therefore, you should take into account the project scope, necessary skill set, and budget before making a decision to hire a JavaScript programmer. This information will assist you in selecting a dependable developer.

3. Conduct Skill Testing Before Scheduling an Interview with a Candidate.

When you’re ready to initiate the process of hiring JavaScript developers, create a job advertisement that details the job responsibilities, ideal candidate’s expected experience and skills, as well as the salary package. You can publish the ad on employment websites like LinkedIn and Indeed or utilize online platforms like Works to locate pre-vetted freelance JavaScript developers.

Finding the perfect candidate for a position may require some time, so it’s crucial to determine the qualifications they must possess. The most in-demand skills usually include…

  • >Proficiency in relevant tech jargon and terminology.
  • Understanding of browsers and servers, including their operation and programming.
  • Aptitude in “Soft” Skills
  • Ability to write tidy and succinct code
  • Stay up-to-date with industry and market advancements.

After identifying potential candidates, schedule meetings with them to gain insights about their experience and determine if they possess the required skills. Evaluate their technical abilities by administering coding assessments and their communication skills through interviews. This will assist you in promptly identifying the most suitable candidate. Given the importance of CSS and HTML for the front end, include questions about them in the front-end test. Additionally, conduct evaluations on the backend for the framework your team will use.

If you opt for an online marketplace to discover a JavaScript Developer, it’s vital to conduct just one round of interviews while asking all the essential questions. Since they have already been pre-vetted, they may not have the time to participate in multiple tests, making this the best approach. It’s critical to act quickly to secure the candidate, as they are in high demand.

4. Appoint JavaScript Programmers with an Exceptional Résumé

Before extending a job offer, it’s crucial to assess a potential employee’s traits. Their portfolio can provide insight into their level of expertise and knowledge, including their qualifications, work history, language and technical proficiency, proficiency in tech stacks, etc. To further evaluate their aptitude in soft skills, discipline, coding prowess, communication skills, learning attitude, etc., reviews from former clients can be consulted.

Careful evaluation of the developer’s past projects is crucial to determine their degree of involvement. Assess the functionality of their websites and apps, as well as their particular expertise, to determine their suitability for the project in question.

5. Hire Full-Time JavaScript Developers with Experience in Open-Source Environments

Developers who possess experience in both open-source and client/company work have a significant advantage. Open-source software is created by a programmer and shared with the programming community at large. When the code is accessible to programmers worldwide, it must be of the highest quality and adaptable to numerous platforms.

The advantages of hiring JavaScript engineers who have experience contributing to open-source projects include the introduction of new ideas to the team. They are also efficient coders with the ability to quickly identify program errors, working well within the team.

6. Don’t Undervalue the Collaborative Skills of JavaScript Developers Purely Based on Their Language of Use

It is commonly thought that programmers are generally solitary individuals lacking social skills and incapable of building strong relationships with their coworkers. However, this is often not the case. No matter the size or scope of the project requiring the use of JavaScript developers, it is crucial for them to hold regular meetings with other team members to discuss objectives, progress, and ideas.

At Works, we seek JavaScript developers with proficient communication and teamwork skills. These competencies are vital to effectively discussing project requirements and challenges with team leads and collaborating with other team members to ensure the development process runs smoothly.

7. Broaden the Types of Questions Asked in Interviews Beyond Purely Technical Ones

It’s not always recommended to rely solely on interviews to evaluate technical competency. For a more precise assessment of a candidate’s abilities, screening exams should be employed. Nevertheless, interviews are an excellent opportunity to test a candidate’s problem-solving skills, creativity, and thinking speed with hypothetical questions. Moreover, by simulating real work scenarios, such questions can help determine if the candidate is suitable for the position.

When hiring a JavaScript developer, it’s recommended to evaluate their social skills, technical proficiency, and problem-solving abilities by asking impromptu problem-solving questions.

8. If Privacy Is a Concern, Look Elsewhere When Searching for JavaScript Developers

Prioritizing the security of users’ personal information is critical. Experienced developers recognize the importance of this issue and take steps to safeguard personal data. The government is taking steps to enhance the security of online systems and safeguard user privacy. It is also essential for organizations to take measures to protect user information from being compromised by malicious actors.

Hiring skilled JavaScript developers who remain informed about the latest security and privacy requirements is crucial to preserve consumer trust and prevent expensive government fines for failing to comply with cybersecurity regulations.

9. Ensure Communication of Plans to the Relevant Parties

When seeking JavaScript developers, it’s critical to guarantee they align with your company’s standards. It’s important to inspect their portfolio for familiarity with the technologies your business employs. Furthermore, it’s vital to ensure that the developer comprehends and is prepared to adhere to your company’s mission, parameters, norms and frameworks during the onboarding process.

Choosing JavaScript developers who share your company’s values is recommended. Additionally, they should possess a solid comprehension of business requirements to ensure projects comply with industry standards and optimize profitability.

10. When Collaborating with JavaScript Developers, Always Verify their References

In the end, while situational questions may provide insight into a candidate’s abilities, they are not foolproof in measuring their collaborative skills. Candidates frequently showcase a positive image and highlight their accomplishments, making it challenging to gauge their competency accurately.

Prior to hiring JavaScript developers, it’s advisable to gather references from prior associates, either from your organization or competitors, or to acquire information on the candidate from their current or previous employer, clients, and colleagues. This will offer a more thorough understanding of the potential candidate.


Once knowledgeable about the traits to pursue and the likely obstacles to circumvent when hiring JavaScript developers, locating and selecting the most suitable candidates is relatively simple. Despite the effort involved, it’s essential to source and appoint capable JavaScript developers.
