Question

I have 4 javascript files (each for a single HTML file) and 3 functions are THE SAME in all 4 files.
I’d like to find a smooth solution that I could somehow include these 3 functions separately… is it possible to include .js within a .js?

Answer 1

1. You can have multiple <script> tags:

   <script src="lib.js"></script>
   <script>
   // do stuff
   </script>
   

2. You can use jQuery:

   $.getScript("lib.js", function() {
     // do stuff
   });
   

3. You can use a pre-processor like browserify or YUICompressor or Google’s Closure Compiler.
