setTimeout (-> alert "later"), 300
setTimeout(function(){ alert("later"); }, 300);
setTimeout(->
alert "later"
, 300)
setTimeout(function(){
alert("later");
}, 300); foo(a, b, c) // functions
(a + b) * c // order of operations
In practice, CoffeeScript can't always guess when something is a function call (such as a function call without arguments), so you end up mixing in some function call usage no matter what.
setTimeout -> (
alert "later"
alert "later"
alert "later"
), 300
setTimeout(->
alert "later"
alert "later"
alert "later"
, 300)
setTimeout(function() {
alert("later");
alert("later");
return alert("later");
}, 300);
