If you are running this script outside of a browser, for example using nodejs, which runs on Chrome's V8 javascript engine: http://nodejs.org/. In nodejs you can create a module and export this module to use in another script. See the following example using nodejs to run:

file1.js:

var exports = module.exports = {};   
exports.f1 = function() {
    console.log('This is from file1.js');
};   

file2.js:

var f = require('./file1.js');

function f2() {
  console.log('This is from file2.js');
}

f2();
f.f1();

Executing the file2.js using nodejs command the output will be:

This is from file2.js
This is from file1.js

But if you are using a browser you can see this: https://stackoverflow.com/a/4634669/2137684
