Mmmm without drastic syntax changes?

Classes:

    There is no semicolon after the function name
    The function keyword is omitted
    There are no commas after each definition

Interpolation:

    `${1 + 1}` <- why not just # like everyone else?

Multi line strings:

     ` Now we have a 3rd
       string delimiter`

Fat arrow:

    $("button").on("click", () => { 
      // really? hanging parens? no function keyword?
    });

Destructuring:

    var [first, , last] = [1, 2, 3]
    // thats a var to assign vals inside an array
    // and just two commas touching to ignore a value

The whole post is about drastic syntax changes. The brackets are optional in coffeescript.

Besides coffeescript is just a tool.
