6:20 That's not quite true, "this" isn't undefined here. If it were, you'd get an exception since you'd be trying to access the "name" field on "undefined". In this case, "this" is actually the global object, i.e. "window" when in a browser context. This is also the same object that holds global variables. So the reason you get undefined is because there is no "name" global.

`fn.apply(this, args)` can be replaced with `fn.apply(null, args)` as for this case we don't actually need to bind the context to any particular object.

I guess LeetCode just used `this` as there needs to be something for the first parameter so `args` can be passed as the second parameter.

Are you guys seeing the syntax highlighting on LC going crazy or is it just me? Getting really annoying 😒😒

I am a begineer to js and leet code i cant understand the logic of this problems i watched this video quite often times but still i am not clear in the why you have returned the fn.apply(this, age) why you have returned this keyword along with the args
