JAVASCRIPT -Versatile Programming Language

You can use it in almost any field from a simple solution to a complex one. This is one of the main reasons for its popularity. Let's see how learning this one language can help you build different kinds of applications in different places…

Web Applications (frontend and backend): JavaScript is very popular in building all web applications. Once you have mastered this language, you can expand your skills to learn other forums and libraries such as React.js, Angular.js, or Vue.js. These libraries and frameworks help you build beautiful web interfaces.
Also, you do not need to spend time learning a new language on the back of your app. With the help of Node.js, Nest.Js, and Express, you can use the same language to build the side of your app. Isn't it cool to be the creator of a complete stack by learning just one language?
Mobile Application: In the early days of smartphone app development you needed to learn Objective-C for iOS and Java for Android. But in the case of JavaScript, both iOS and Android applications can be created using React Native. You can also use Flutter, Ionic or alternative
Companies such as Apple and Google have adopted this language in their mobile device development tools to extend their development base. Also, PhoneGap which is a framework for mobile application development allows you to create custom-like functionality with JavaScript API calls.
Desktop Applications: You can create a desktop application with the help of ElectronJS.
Big Data and Cloud Development: NoSQL databases like MongoDB and others use JSON (JavaScript object notation) on today's web data exchange web. The JSON document has become the standard for archiving records. JSON works well with most programming languages but it is best equivalent to JavaScript to connect an app with big data.
Node.js is also better suited for a cloud application. It is one of the top four languages supported by major cloud platforms such as Google, Amazon, and Microsoft Azure. Development with Node.js is growing rapidly and now has 35,000 downloads with more than 88,000 modules.
Blockchain Technology: You can also use JavaScript to get a backend solution for blockchain technology and work with smart Ethereum contracts. You can create smart contracts with Solidity (another version of JavaScript with limited functionality) which is a special programming language designed for this purpose.
Default: Even if you don't want to be an engineer, you can use this language to change your daily commute. You can create other simple programs to avoid repetitive tasks like reviewing a few things in several places or following people on Instagram. You can create dynamic Mac computer screens using JXA. You can also create dynamic Photoshop settings. So many annoying and time-consuming things can be done in this language.
You can use ExcelJS to create tools intended for editing files in XLS format.
JavaScript is an excellent language for creating visual effects and that is why it is also ideal for game development (Unity)
It can be used to enable smart TV or you can create music with it.
