Can we import .js file?

We can include a JavaScript file in another JavaScript file using the native ES6 module system. This allows us to share code between different JavaScript files and achieve modularity in the code. There are other ways to include a JS file like Node JS require, jQuery's getScript function, and Fetch Loading.
