spacing.js

// include a space after most keywords (eg var, if, else, for, return)
var foo = "bar";

// include a space around operators
foo === "bar";
foo += "qux";

// put a space after most closing parentheses

// indent within if statements
if (foo === "bar") {
  alert("baz!");
}

// indent within loops

for (var i = 0; i < 3; i++) {
  alert(i);
}

// indent within functions
function doSomething() {
  alert("do something you fool!");
}

// always indent two spaces at a time. never more, never less.

// don't include a space between a function and the opening parentheses enclosing its arguments
alert("look, no space!");
