There has been a quite a bit of chatter recently on whether or not you should use semicolons in your JavaScript code.
JavaScript provides a feature called Automatic Semicolon Insertion (ASI). For the most part there are rarely problems in omitting semicolons, but there are a few cases where semicolons are required to prevent syntax errors or resolve code ambiguities.
In the past it was very common to see global variables in snippets of JavaScript code across the web, such as:
name = "Spock"; function greeting() { return "Hello " + name; }
A better approach is to place all of your code within a namespace; an object that contains all of your code and helps to prevent name clashes with JavaScript code written by others.
