Chain function call after function definition [duplicate]

How can I chain a function call after a function definition in CoffeeScript?

Equivalent javascript would be:

var foo = function () {
    // stuff
}.bar()

The only way I managed to do it is:

foo = `function () {
    // stuff
}.bar()`

But I hope for a better solution than embedding javascript in my (beautiful) coffeescript code

回答1:

Try like this:

foo = (-> stuff).bar()

For example:

square = ((x)-> x*x).bar()

Compiles into:

var square;
square = (function(x) {
  return x * x;
}).bar();
