Confusing info about js-function-context-this

[gaand]

Could we add

foo.call( obj2 ) // this === obj2
obj1.foo() // this === obj1

Also, could we not use the name foo in different ways in this list (uncapitalized constructor function, method - key lookup in an object, a regular function, yada)?

Binding isn't a very good word here, either.

[jrhorn424]

obj1.foo().call(someOtherObject)

That's an explicit binding, which is not what the quoted text is referring to.

Is the function called with a context (implicit binding)

I think the parenthetical is important. It should be a parenthetical.

I'm not sure when to re-emphasize that this is not determined until the function is called. It's one of those things, like the definition of a callback, that I drill into them when I deliver this talk.

Yeah. I drilled it too. Maybe that has to be enough?

After discussing with @gaand, the example would be more appropriately shown as:

obj1.foo() // this === obj1
obj1.foo.call( obj2 ) // this === obj2
