So I have File1.js that has the main functions for my program. I also have File2.js that has extra functions that I didn't want to include in File1.js because I feel it would be easier to edit the functions in a separate file. Is it possible to call a function in File1.js and have the function defined in File2.js? If so, how can I link the two files together?

  • You could look into using a build tool to concatenate the files together. Otherwise, if you have both file1.js and file2.js linked to in a HTML document, all methods in file1.js should be available within file2.js. – Pytth May 13 '19 at 23:19

  • As you've tagged this `node.js`, the mention of `HTML` is confusing - since node.js is not a browser, therefore there is no HTML – Jaromanda X May 13 '19 at 23:21
  • nodejs supports [modules](https://nodejs.org/api/modules.html#modules_modules) –  May 13 '19 at 23:22

You can do so by declaring exports like so:

/* utils.js */
module.exports = {
  doSomething: function() {
    // code
  },

  anotherOne: function() {
    // code
  }
};

/* index.js */
const utils = require('./utils.js');
utils.doSomething();
