I've never hear of snippets before, what is it

Snippets Are...

Snippets are little small pieces of script codes you can insert into your current scripts. Functions are a very common type of snippets programmers use to include in their scripts. It saves alot of time when repetative code is required. Snippets have advanced properties; they support the use of Interpolation Shortcuts, can be assigned to Key Bindings, and allow for the specification of indentation context and cursor position.
