Don't use a space!

// coffeescript
beforeNode = children[children.length-1]

Or use a space on each side of the -

// coffeescript
beforeNode = children[children.length - 1]

Results in

// js
var beforeNode;

beforeNode = children[children.length - 1];

Or use two spaces!

# coffeescript
beforeNode = children[children.length - 1]

Results in 

// javascript
var beforeNode;

beforeNode = children[children.length - 1];
