@babel/plugin-transform-arrow-functions

What is @babel/plugin-transform-arrow-functions?

The @babel/plugin-transform-arrow-functions package is a plugin for Babel, a JavaScript compiler, that transforms arrow function syntax into function expressions. This transformation is particularly useful for ensuring compatibility with environments that do not support ES6 arrow functions.

What are @babel/plugin-transform-arrow-functions's main functionalities?

Transform arrow functions to function expressions

Converts ES6 arrow functions into equivalent ES5 function expressions. For example, the arrow function `() => 5` gets transformed into a function expression `function() { return 5; }`.

"use strict";\n\nvar a = function a() {\n  return 5;\n};"
