Why Should a Developer Work with Javascript Even if They Plan to Use React.js, Nest.js, or Next.js

Are you a JavaScript developer looking to improve your skills? If so, you should consider exploring the potential of JavaScript to help you create dynamic webpages. By studying JavaScript, you can gain a better understanding of React.JS, Nest.JS, and Next.JS and enhance your development capabilities. To learn more, please read on.

Sharafat Ahmed, a software engineer at Works, was recently interviewed and provided extensive responses to the most common queries related to JavaScript, Nest.JS, React.JS, and Next.JS. Mr. Ahmed gave a thorough and insightful account of the nuances of each technology, allowing the interviewer to gain a better understanding of how these technologies can be used to create powerful web applications.

This article presents the most important takeaways from the conversation.

When asked, “What is JavaScript?”

JavaScript is a widely-used programming language that enables the creation of both client-side and server-side applications. It is entirely written in text, and is one of the fundamentals of modern web development, alongside HTML and CSS. HTML is the foundation and content provider for a website, while CSS offers a range of design possibilities. All HTML documents contain a Document Object Model (DOM), providing an organised representation of a document’s contents.

JavaScript is a powerful and versatile language that can be used for a variety of purposes. It is often used to create mobile and web applications, websites, server applications, and games. Its ability to access and modify Document Object Models (DOMs) allows it to modify HTML and CSS components, verify data, integrate multimedia, create dropdowns and menus, and more, which helps to transform static web pages into interactive ones.

How steep is JavaScript’s learning curve?

When it comes to computer languages, JavaScript is widely regarded as one of the most straightforward to learn. For those with prior experience in HTML and CSS, mastering JavaScript should be relatively straightforward. Indeed, it is possible for programmers to gain a fundamental understanding of JavaScript and other coding languages within a matter of months. Nevertheless, it is important to note that JavaScript requires adherence to a well-defined code structure. Therefore, developers must exercise caution when creating and testing their code.

Do you agree that JavaScript has fundamentally altered the web development landscape?

Initially developed in 1995, JavaScript lagged behind other popular programming languages such as Java, C and C++ in gaining recognition. However, Netscape made the decision to incorporate JavaScript functionality into their web browser in 1996, leading Internet Explorer and Firefox to follow suit in 1997 and 2000 respectively.

Ultimately, all major web browsers adopted support for JavaScript, making it the language of preference for web development. Consequently, regardless of the language used for back-end development, JavaScript is the go-to language for front-end development.

In what ways will developers benefit from having knowledge of JavaScript?

Overall, the software industry has undergone continual transformation over the years. Contrary to expectations, support for traditional programming languages such as Java and PHP has not diminished, but continues to be highly sought after. Furthermore, since the launch of React.JS a decade ago, JavaScript has become the most widely adopted library.

As a web developer who is proficient in JavaScript, you can take advantage of any of the above-mentioned technologies in your projects. Additionally, the software industry is likely to present new skills and opportunities in the near future. JavaScript is one of the most widely used computer programming languages in the world, so it is certainly beneficial for web developers to be able to utilise it. Furthermore, with the release of Node.js in 2009, developers started to use JavaScript for server-side development.

What strategies should JavaScript programmers use to ensure their work remains relevant in the dynamic software market?

As a JavaScript developer, it is critical to stay up-to-date on the latest trends and techniques in the software industry. This requires consistently learning new skills and leveraging JavaScript’s versatility to adapt to multiple projects. Keeping abreast of new technologies allows programmers to remain competitive and develop strong, marketable skills.

Any front-end developer who is serious about their profession should supplement their existing skills by engaging in back-end programming periodically. Furthermore, back-end developers should broaden their knowledge by learning and applying JavaScript through projects such as DevOps. This will enable them to expand their abilities and increase their value to employers.

To what extent does familiarity with JavaScript facilitate study of other languages and frameworks?

It is widely accepted that there are many similarities between computer languages and web frameworks. For web developers with a good understanding of JavaScript, there are plenty of opportunities to explore and develop a deeper understanding of the fundamentals of their platforms. JavaScript is an incredibly useful language for programming both the front-end and back-end of a website. As developers become more proficient in JavaScript, they will be better equipped to utilise and incorporate the latest tools and techniques. JavaScript frameworks offer developers a vast array of pre-written code libraries, which can be easily implemented by those with experience in JavaScript.

What exactly differentiates React.JS, Nest.JS, and Next.JS from these other JavaScript frameworks?

Which of React.JS, Nest.JS, and Next.JS should novice JavaScript developers focus on learning first?

Having previously worked as a Java developer, I decided to switch to React.JS and Nest.JS. It is important for developers to master JavaScript before attempting to learn any of these frameworks, as it is the foundation of these technologies.

For those aspiring to pursue a career in front-end development, acquiring a mastery of JavaScript is essential. Once a developer has become well-versed in JavaScript, they should then progress to React.JS. Those who are already familiar with React’s architecture, tools, and setup should have no difficulty in mastering Next.JS.

For those aspiring to develop software on the back end, Nest.JS is their best bet. This JavaScript framework is comparable to Spring Boot, a popular Java web framework, so it is relatively straightforward for experienced Java developers to pick up.

How does one become a React.JS, Nest.JS, or Next.JS developer?

React.JS developers can expect to find excellent job opportunities with top companies all over the world. Possessing expertise in this programming language will open doors to a wide range of career possibilities. Additionally, it is easy to learn React Native, a cross-platform mobile application framework, since it is based on React.JS. This could lead to significant professional advancement for React.JS programmers.

With its increasing popularity, Next.JS, a framework built on top of React.JS, is in high demand. For those looking to pursue a career as a Next.JS programmer, a solid understanding of React.JS will be essential for success. With the growing demand for Next.JS, developers specialising in this framework can expect a promising and lucrative future.

Nest.JS is an outstanding JavaScript framework that enables developers to create code that is both legible and can be easily extended. As microservices architecture continues to increase in popularity, leading companies around the world are actively looking for experienced Nest.JS developers to join their teams.

If you were to provide advise to a JavaScript developer who was going in for an interview, what would it be?

Individuals who are searching for a role as a developer should be sure to become acquainted with the fundamentals and concepts of JavaScript prior to attending an interview. To ensure that you are fully prepared for the interview, it is recommended that you thoroughly review the primary documentation of the associated programming language. It may be beneficial for developers to watch instructional videos and read educational material found on the internet. Furthermore, Kyle Simpson’s book, “You don’t know JS” is a remarkable tutorial for those wishing to learn JavaScript.

Will my knowledge of JavaScript, React.JS, Nest.JS, and Next.JS help me get a well-paying job?
