JavaScript Introduction to Programming Basics Variables

Why all the console.log entries?

In this video he shows doing console.log entries for a bunch of stuff like "Hello from [file name] and "Hello Again". I assume these are to show how to do console.log entries, but then he shows doing an entry with a result different than the prompt entry. Why is that? What is the general purpose/benefit to console.log entries? (I'm sure it's covered later but I think knowing the "why" of it all now will help me understand all the lessons better.)

Thanks!

Hi Stacy,

console.log() is used to display something for you as a programmer. Let's say you want to know a value of a variable which changes when the script runS, so you use console.log to print out the variable for you. Console.log has no impact on the visitors of the page but it may be useful for your to check the functionality of the code and understand what is going on for example if something works differently to what you have expected.
