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

If you’re a developer with a focus on JavaScript, you should consider exploring the wide range of possibilities it offers for developing dynamic webpages. Studying JavaScript can help you become proficient in React.JS, Nest.JS, and Next.JS, and thus augment your development abilities. To know more, keep reading.

In a recent interview, Sharafat Ahmed, a software engineer at Works, answered various frequently asked questions about JavaScript, Nest.JS, React.JS, and Next.JS. Mr. Ahmed’s detailed and perceptive responses provided the interviewer with a deeper insight into these technologies and their potential to create robust web applications.

The following article lists the key points from the aforementioned discussion.

When asked the question, “What exactly is JavaScript?”

JavaScript is an extensively employed programming language that makes it possible to produce client-side as well as server-side applications. It’s developed entirely in text and is one of the primary components of contemporary web development, along with HTML and CSS. While HTML provides the foundation and content of a website, CSS provides a range of design options. Every HTML document has a Document Object Model (DOM), which provides an orderly representation of the contents of a document.

JavaScript is an adaptable and potent language that serves various purposes. It’s commonly used in creating mobile and web applications, websites, games, and server applications. Its capability to access and modify Document Object Models (DOMs) enables it to modify HTML and CSS elements, authenticate data, integrate multimedia, create dropdown menus, and much more. This transforms static web pages into interactive ones.

How challenging is it to learn JavaScript?

In the realm of computer languages, JavaScript is commonly considered one of the most uncomplicated to learn. For individuals with prior knowledge of HTML and CSS, mastering JavaScript might be fairly simple. In fact, programmers can gain a fundamental understanding of JavaScript and other programming languages within a few months. That being said, it’s important to note that JavaScript requires adherence to a well-defined code structure, thus developers should be mindful when creating and testing their code.

Do you concur that JavaScript has significantly transformed the landscape of web development?

Originally developed in 1995, JavaScript was outpaced by other prominent programming languages like Java, C, and C++, in gaining recognition. Nevertheless, Netscape’s decision to incorporate JavaScript functionality into their web browser in 1996 initiated a trend followed by Internet Explorer in 1997 and Firefox in 2000.

In the end, all major web browsers embraced support for JavaScript, making it the favoured language for web development. As a result, despite the choice of back-end development languages, JavaScript remains the primary language for front-end development.

What advantages do developers gain from possessing JavaScript proficiency?

The software industry, on the whole, has been in a state of constant evolution over the years. Ironically, support for traditional programming languages like Java and PHP, far from declining, remains in high demand. Moreover, since the introduction of React.JS ten years ago, JavaScript has emerged as the most widely adopted library.

As a web developer with expertise in JavaScript, you have the advantage of leveraging any of the aforementioned technologies in your projects. Additionally, the software industry is likely to offer new abilities and prospects in the immediate future. JavaScript is one of the world’s most extensively used programming languages, making it highly advantageous for web developers to be proficient in it. Moreover, with Node.js being released in 2009, developers began using JavaScript for server-side development.

What tactics can JavaScript developers utilise to ensure that their work remains pertinent in the high-paced software industry?

For JavaScript developers, it’s vital to be aware of the most up-to-date trends and techniques in the software industry. This entails continually acquiring new abilities and utilizing the flexibility of JavaScript to tackle multiple projects. Keeping track of emerging technologies enables programmers to stay competitive and develop valuable, in-demand skills.

A front-end developer who takes their profession seriously should intermittently enhance their current skills by engaging in back-end programming. In addition, back-end developers should broaden their knowledge by acquiring and using JavaScript through projects like DevOps. This enables them to extend their abilities and enhance their worth to employers.

In what way does familiarity with JavaScript ease the learning of other languages and frameworks?

It is widely acknowledged that computer languages and web frameworks share numerous similarities. For web developers with a solid grasp of JavaScript, there are many avenues for exploring and gaining a deeper appreciation of their platforms’ fundamentals. JavaScript is an incredibly versatile language for programming the front-end and back-end of a website. As developers become more adept in JavaScript, they will be better positioned to utilise and incorporate the most up-to-date tools and techniques. With experience in JavaScript, developers can easily implement pre-written code libraries offered by JavaScript frameworks.

What sets React.JS, Nest.JS, and Next.JS apart from other JavaScript frameworks?

For novice JavaScript developers, which framework – React.JS, Nest.JS, or Next.JS – is the most important to learn first?

As a former Java developer, I transitioned to working with React.JS and Nest.JS. It’s essential for developers to have a strong grip on JavaScript before delving into any of these frameworks since it’s the basis of these technologies.

For those aiming to establish their careers in front-end development, mastering JavaScript is imperative. After attaining proficiency in JavaScript, developers should then advance to React.JS. Those already acquainted with React’s architecture, tools, and configuration should find it easy to master Next.JS.

For those aspiring to design back-end software, Nest.JS is an ideal choice. This JavaScript framework has similarities to Spring Boot, a prevalent Java web framework, making it relatively simple for seasoned Java developers to grasp.

What are the steps to becoming a developer for React.JS, Nest.JS, or Next.JS?

React.JS developers can anticipate finding outstanding employment possibilities with leading businesses worldwide. Having proficiency in this programming language will unlock various career options. Furthermore, it’s simple to learn React Native, a cross-platform mobile application framework, since it’s based on React.JS. This could lead to significant career advancement for React.JS developers.

As its popularity surges, there is high demand for Next.JS, a framework built on React.JS. To excel as a Next.JS programmer, a sound comprehension of React.JS is critical. Developers who specialise in this framework can anticipate a promising and remunerative future due to the rising demand for Next.JS.

Nest.JS is an exceptional JavaScript framework that allows developers to write readable code that can be easily expanded. As the prevalence of microservices architecture continues to grow, prominent companies across the globe actively seek experienced Nest.JS developers to join their teams.

What advice would you give to a JavaScript developer going for an interview?

Aspiring developers should have a strong grasp of the fundamentals and concepts of JavaScript before attending an interview. To ensure that you are thoroughly prepared, it’s recommended that you carefully review the primary documentation of the relevant programming language. Watching educational videos and reading online learning materials may also be beneficial for developers. Moreover, Kyle Simpson’s book, “You don’t know JS”, is an excellent guide for those looking to learn JavaScript.
