With this fragment of code in coffeecript:

beforeNode = children[  children.length -1 ]

coffescript generate:

beforeNode = children[children.length(-1)];

How can I write source in coffescript to generate expected javascript code?

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];

I would prefer instead to use a space between - and 1... i.e., beforeNode = children[children.length - 1].

@GauthamBadhrinathan updated answer to show this is possible too

Or use two spaces!

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

Results in

// javascript
var beforeNode;

beforeNode = children[children.length - 1];
