Javascript create library of functions. Create and use "plug-and-play" routines To create a reusable plug-and-play routine, simply enclose it within a function in a JavaScript program. After it has been fully debugged, you can copy the... Functions — reusable blocks of code. Another essential concept in coding is functions, which allow you to store a piece of code that does a single task inside a defined block, and then call that code whenever you need it using a single short command — rather than having to type out the same code multiple times.

If you prefer to create your library in the simplest way possible, you can simply type your code into a JavaScript file and place this file in every project you want to use.
