Babel is a Javascript toolchain used to convert later versions of Javascript to es5 or EcmaScript 2009. Even though supporting the latest versions of Javascript in older functions is the core functionality of Babel, it is not it’s only functionality. It performs other tasks like transforming syntax, Code mods, polyfills, etc.
React JS uses a custom babe plugin to convert JSX to plain Javascript code, whereas VueJs uses a custom compiler to convert .vue files to plain Javascript.
The above JSX code is converted to the following code snippet by Babel.
Using Babel as a compiler gives React developers the flexibility of a commonly used toolchain and the freedom to focus more on the library itself instead of spending too much time on building the compiler. Babel also helps developers use the latest Javascript features without worrying about support for said features in older browsers.
The beauty of Babel is that the changes are done during runtime, thus it does not affect performance greatly. Babel basically converts the latest Javascript syntax into equivalent syntax in ES5. This does not translate to reduced performance as most syntax changes after ES5 are just wrapper implementations with no or negligible performance improvement.
The above ES6 Arrow function is converted to the following by Babel
However, with most modern browsers have already implemented nearly all features of es6 and with the latest version of NodeJs completely supporting es6, the requirement for Babel is reduced greatly.
However, writing code in React without Babel will make development very difficult. The only way to accomplish this is to use React API’s like React.createElement instead of JSX.
Babel is invaluable when the support of older browsers like IE10 & IE 11 etc is required. Babel also helps perform large scale refactors within the applications by code-mods (or code modifications) where old versions of a piece of code can be changed across the application during the build process instead of manually changing the code throughout the application which increases the possibility of errors.
In conclusion, Babel is not required for small projects which do not require older browser support or if the developer does not use Javascript syntax introduced after ES5.
Babel is a free and open-source JavaScript transcompiler that is mainly used to convert ECMAScript 2015+ (ES6+) code into backwards-compatible JavaScript code that can be run by older JavaScript engines. It allows web developers to take advantage of the newest features of the language.

may not be essential for small projects or environments with robust ES6 support, its significance becomes evident in scenarios requiring compatibility with older browsers or facilitating large-scale code transformations.
However, Babel still has a lot to offer. It can change your code in special ways, add features so your code works on old browsers, and has a lot of plugins for doing different things. Babel isn't always needed, but it can make your projects better in many cases.
Incorporating Babel into the development workflow not only facilitates the use of modern JavaScript features but also enhances code quality, team collaboration, and application performance. Its versatility and compatibility with various tools make it an indispensable asset in modern web development.

Babel is a very famous transpiler that basically allows us to use future JavaScript in today's browsers. In simple words, it can convert the latest version of JavaScript code into the one that the browser understands.
Conclusion. In conclusion, while Babel may not be essential for small projects or environments with robust ES6 support, its significance becomes evident in scenarios requiring compatibility with older browsers or facilitating large-scale code transformations.
Babel is a powerful JavaScript compiler that has become an indispensable tool for developers, especially those building React applications. At its core, Babel's primary function is to transform cutting-edge JavaScript code into versions of JavaScript that can be interpreted by older browsers.
The Next.js Compiler, written in Rust using SWC , allows Next.js to transform and minify your JavaScript code for production. This replaces Babel for individual files and Terser for minifying output bundles. Compilation using the Next.js Compiler is 17x faster than Babel and enabled by default since Next.js version 12.
Well, Babel is capable of converting JSX to JavaScript - the TypeScript compiler can't do this. So, if your project is built using React, you will need Babel. If a project already uses Babel, it is simpler for that to take full responsibility for all the transpilation.
Babel, a JavaScript compiler, ensures cross-browser compatibility and enables using modern language features. Integrating both tools enhances code organization and performance.

You should not be using babel-node in production. It is unnecessarily heavy, with high memory usage due to the cache being stored in memory. You will also always experience a startup performance penalty as the entire app needs to be compiled on the fly.
React doesn't "need" babel or webpack but the library is built on the concept of using ES6 javascript syntax and JSX (essentially HTML in JS). React however can be used without ES6 and JSX which would remove the initial need for Babel but you would lose the potential benefits of ES6 and JSX.
There are disadvantages to using Babel. The fact that Babel code changes the syntax while transpilation makes the code difficult to understand. The size of the code that is transpiled can be increased as well.
The Tower of Babel stood at the very heart of the vibrant metropolis of Babylon in what is today Iraq. It was a city of open squares, broad boulevards and narrow, winding lanes. But the City of Cities, as Babylon was known by the Ancients, eventually fell into ruin.
