re: Is `this` in Javascript bad? VIEW POST


It is only when call, bind and apply are used for the wrong reasons - or excessively - that this starts to get unpredictable. In my opinion this is the exact thing that makes Javascript as powerful as it is.

this always points to the context of the call to the function within which the keyword is used.

Arrow functions do what they do because the above statement does not apply to them. Instead, they inherit their this value from their declaration context.

That's all there is to it. It is never arbitrary, nor should it be difficult to determine, where this points to. I think it's just a matter of awareness of the fact that you'll have to look for its value at the preceding call stack, instead of it's lexical scope.
