8,730 PointsJS Execution
What is the process by which scripts are executed? The reason I ask is because I want to be able to run the scripts I am learning here in other places. For this reason I make sure that everything i do in Treehouse i can also replicate in Cloud 9. This has worked for HTML and CSS but even these first simple commands in JS do not execute. Thank you.

That being said, JavaScript can be run a number of different ways. You can define a function and have it run on initial page loading, you can have a piece of code that is continuously running in the background, or you can bind listeners to elements so that code is only executed when certain actions are taken. Some pages use none of these methods, and some use one or more (or even a combination of them).
I'm no JavaScript expert, so I'm sure there are others, but I think that's the gist of what you were wondering.
