What is javascript collision?

Question

Any best practices around him?

Answer 1

A JavaScript collision is when you have two global objects with the same name, and one another. For example, you can reference two libraries that use a function named $ in the root object (window) for the query function. The idea is that you should use as few global objects as possible. The best way to do this is to create a namespace for any JS you write, like any other language:

var myApplication = {};

Then add any of the following functions / objects inside the namespace:

myApplication.init = function () {

}

My teacher was not very clear on this issue, however ...
