How can I put multiple items into a JSON object with CoffeeScript?

Question

  categories = {{"code": "zzz", "title": "Electronics"}, {"code": "yyy", "title": "Cars"}};

That's my JavaScript. What's the equivalent CoffeeScript?

Answer 1

Braces are optional in CoffeeScript, you can have either this:

categories = [
  code  : 'zzz'
  title : 'Electronics'
,
  code  : 'yyy'
  title : 'Mechanics'
]

(notice the unindented comma) or the more obvious:

categories = [
  {
    code  : 'zzz'
    title : 'Electronics'
  }, // comma optional
  {
    code  : 'yyy'
    title : 'Mechanics'
  }
]

Answer 2

First of all, I think your JavaScript should look like this:

categories = [{"code": "zzz", "title": "Electronics"}, {"code": "yyy", "title": "Cars"}];

You do want an array, correct? Then the CoffeeScript is, well, exactly the same (without the trailing semicolon but that's also optional in JavaScript):

categories = [{"code": "zzz", "title": "Electronics"}, {"code": "yyy", "title": "Cars"}]

There's a "TRY COFFEESCRIPT" button at the top of the Github CoffeeScript page that you might find useful for things like this.
