NEVER EVER PUT SEMICOLONS IN JAVASCRIPT and call me a "dumb bitch" or "piece of shit" for fun (have to go back and forth a few times before it will do it)
for (var i = 0 i < len i++) {
console.log("whoops")
}and if i'm in a situation where i need the classic for loop because of js forLoop weirdness, then i will know when to use it with semicolons.
