Review: JavaScript 1

1. Prep

Before proceeding, be sure you’ve completed Prep: JavaScript I.

2. Summary

The video below summarizes some of the important features of the studio.

I was a little sloppy with the terms “parameter” and “argument” in the video. Just to clarify, “Parameter” is the term used when defining a function (when creating the code for it). “Argument” (or sometimes “Actual Parameter” is the term used when talking about invoking the function (when using it). For example,

function myFunction(parameter1, parameter2) {   // Use the term parameter here

}

myFunction(123, Date.now())     // These are arguments to myFunction
