Scope has two parts, global and local. Scope has to do with Variables and using these variables within your code and more specifically functions. Global variables can be used all around in your code. Local variables are specific to their parent functions. | |
Global variables are avoided because they can be called within functions and potentially changed or altered created hard to find bugs. | |
Strict mode in JS helps the user write strict code. for example, foo = "foo fee foo foam"; is not strict. It is missing the Var keyword. This needs to be added in. STrict enforces the Var keyword use on all variables. | |
