Question

Say I’ve got the code:

cat = {
    feed: (food) ->
        alert "cat ate #{food}"
}

pets = {
    "maximus": cat
}

getPet = (name) ->
    pets[name]

How can I invoke the “feed” method of returned by “getPet” cat object? This is not a valid code:

getPet "maximus" feed "Fish"

In plain javascript it would look like this:

getPet("maximus").feed("Fish");

Answer 1

You can’t do chaining without the parentheses on the left-most parts of the chain.

getPet('maximus').feed 'fish'
