Semicolons in JavaScript are Optional

JavaScript is a scripting language where semicolons as statement terminators are optional. I have never found a conversation about this, I just stumbled across one and found it interesting.

Some of the points the author makes about why you should use semicolons are:
  • Spec is cryptic and JavaScript implementations differ
  • You can't minify JavaScript code without semicolons
  • It's good coding style
  • Semicolon insertion bites back in return statements
I am pretty obsessive about using semi-colons in my JavaScript. It just makes it neat and organized in my opinion. Also keeps me in sync with my PHP programming as well.
