Why Should React.JS, Nest.JS, and Next.JS Developers Master JavaScript?

JavaScript is a text-based programming language used for developing client-side and serve-side applications. JavaScript is one of the essentials of web technology, along with HTML and CSS. HTML provides the web page’s structure and content, whereas CSS offers different styling options for the website. Every webpage includes a document object model (DOM) that represents the page’s content in an organized form using HTML. 

JavaScript is used for creating mobile and web applications, building web servers, and developing server applications and games, among others. JavaScript can easily access and manipulate the DOM of every webpage. Thus, JavaScript turns static web pages into interactive pages by modifying HTML and CSS elements, validating data, adding multimedia, inserting dropdowns and menu options, etc. 

JavaScript is one of the easiest programming languages to learn. Developers familiar with HTML and CSS can learn JavaScript with ease. Also, developers can learn how to code and other basic JavaScript operations in a few months. Developers must ensure to write and test the code thoroughly since mastering JavaScript requires following a well-defined code structure.  

Invented in 1995 after programming languages like Java, C, and C++, JavaScript did not become popular right away. After Netscape added support for JavaScript in 1996, Internet Explorer and Firefox also added support for the programming language in 1997 and 2000, respectively. 

Soon every major browser offered support for JavaScript. And thus, JavaScript became the de-facto programming language for web development. Sure, developers can choose different languages for back-end development, but JavaScript is the go-to choice for front-end development. 

The software industry is an ever-changing landscape. However, old languages like Java and PHP are still in demand despite people assuming that such technologies will become extinct. Also, in the past 10 years since the launch of React.JS, the JavaScript library has been the most popular.

Learning JavaScript allows developers to utilize all the above-mentioned technologies seamlessly in different projects. Also, the software industry can see the emergence of new skills in the near future. This can benefit the developers well versed in JavaScript as the programming language is one of the mainstays of web technology. Also, with the release of Node.js in 2009, developers started using JavaScript for backend development.

JavaScript developers can stay relevant in the fast-changing software industry by learning new things. Since JavaScript is a versatile language, developers must work on different projects. 

Developers working on the front-end must try back-end development to enhance their skillset. Similarly, developers working on the back end should take up DevOps or other projects that expand the knowledge and utilization of JavaScript. 

Most of the programming languages and web frameworks have many similarities. Mastering JavaScript enables developers to add to the core working knowledge of a website. JavaScript helps with front-end and back-end development. Developers who develop a deeper understanding of JavaScript can integrate the programming language with new skills and technologies. Also, JavaScript frameworks are a collection of JavaScript code libraries that developers who know JavaScript can utilize with ease.

Nest.JS vs React.JS vs Next.JS

What should developers who are starting their journey with JavaScript pick from React.JS, Nest.JS, and Next.JS?

I was a Java developer for some time before using React.JS and Nest.JS. Before learning any of the three frameworks, developers must learn JavaScript as it is the building block of such technologies. 

Developers who want to work on the front-end must go for React.JS after learning JavaScript. Similarly, developers who are familiar with the structure, tooling, and configuration of React can learn Next.JS. 

Developers keen to work on the back-end must choose Nest.JS after learning JavaScript. Developers with previous working experience with Java can easily learn Nest.JS as it is similar to Spring Boot, a Java web framework.

What does the career path of a React.JS, Nest.JS, and Next.JS developer look like?

React.JS offers great job opportunities for skilled developers. Top organizations around the world are hiring React.JS developers. React.JS developers find it easy to learn React Native, a cross-platform mobile development framework that can ensure good career growth. 

Next.JS is a framework on top of React.JS that offers good job opportunities. Developers applying for jobs that require knowledge of Next.JS must also be familiar with React.JS. Next.JS developers have a good career path ahead as the popularity of the framework is growing. 

Nest.JS is a great back-end JavaScript framework that helps developers write maintainable and scalable code. Top companies worldwide are looking for Nest.JS developers as the software industry embraces microservices architecture. 

Developers preparing for an interview must master JavaScript’s basics and core concepts. Also, studying the original programming language documentation is necessary to clear all doubts. Referring to video tutorials and online study material can also help developers. In addition, a great book to learn JavaScript is ‘You don’t know JS’ by Kyle Simpson.
