Why I can't pass console.log as a callback argument in Chrome (and Safari)?

Question

The following snippet will produce an error in Chrome (and Safari) while it works in Firefox.

I'd expect to have 2 numbers shown in javascript console, but in Chrome I only get the first and then an Uncaught TypeError: Illegal invocation

// a generic promise that return a random float
var makePromise = function() {
  return $.Deferred().resolve(Math.random());
}

// This works in all browsers
makePromise().then(function(d) {
  console.log(d);
});
// This works in firefox only
makePromise().then(console.log);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Why is this happening?

Side note: my question is not the same as this question.

Update

Thanks to comments and answer to use console.log as callback one need to do

makePromise().then(console.log.bind(console));

Answer 1

In a chromebook I can duplicate the problem as follows:

function do4(cb){ cb(1); cb(2); cb(3); cb(4); }

do4(console.log)
VM1491:2 Uncaught TypeError: Illegal invocation
    at do4 (<anonymous>:2:19)
    at <anonymous>:2:12
    at Object.InjectedScript._evaluateOn (<anonymous>:905:140)
    at Object.InjectedScript._evaluateAndWrap (<anonymous>:838:34)
    at Object.InjectedScript.evaluate (<anonymous>:694:21)do4 @ VM1491:2(anonymous function) @ VM1552:2InjectedScript._evaluateOn @ VM1288:905InjectedScript._evaluateAndWrap @ VM1288:838InjectedScript.evaluate @ VM1288:694

But this works fine, and indeed points toward the problem:

do4(console.log.bind(console))
VM1491:2 1
VM1491:2 2
VM1491:2 3
VM1491:2 4

Why is that?

In chrome, console by itself returns an Object of prototype Console, look:

console
Console {} memory: MemoryInfo__proto__: Console

It may seem odd thinking of console as an Object, but it is. console has several other lesser-used methods that are not used as often as console.log but are documented in MDN Console Docs and Chrome Console Docs

And here we get to a big Javascript-ism that can confuse people:

Javascript methods are unbound methods. That is, the methods are not bound to any particular object.

So console.log is a function, but it is the function only and does not preserve its binding of this to console.

The variable binding is referred to inside a function's code by a magic this variable, which can be set with function.bind or function.apply.

When console.log() is called, JS does the binding of the function code's this to the console object. But when console.log is merely passed as a function, it does not do the binding, so that other code can use it more flexibly. This behavior is inconvenient with console.log and many other methods, but in some cases adds needed flexibility.
