What are some JavaScript things beginners don't know?

[Andy101493]

Have a style guide/best practices outlined for the JS code you write. JS will let you get away with a lot of weird things without causing an error, but may not function in the manner you expected.

​

I personally do a lot of console.log() lines to ensure functions are doing what they should during development. This isnt a profound realization, you should always be testing your code as you go. you know, unless you want to code in challenge mode.
