    English isn't my first language, but the way you are explaining - everything is accessebly!
    Thank you! Even reading in native language can't help me understand it so clear.

    It's super nice to use diagrams and simple examples (addition of numbers) to demonstrate the concepts. The concept itself, to a beginner, is hard to master. It will be more confusing if sophisticated example is used, but you use a very simple example. Thanks a lot.

    You can also do: var bound = addToThis.bind(obj, 1, 2) to hard code the arguments.
    Then you can pass the last argument, for example, console.log(bound(3))

    8:10 difference between call and apply: call() is used for function arguments, apply() is used for array values

  • @eahofer
    @eahofer 7 років тому +1

    Agreed, concise. In short:-
    CALL = allows to bind a function to an object passed in at runtime (e.g. functionname.call(object, arguments) where inside of functionname, "this" serves as the pointer to the object) with immediate result
    BIND = alternative to CALL that gives you a function for later use

      hi Rishi , i understood the call, apply & bind as various ways of printing output. If one method works well, why the other two ? what is the added advantage of having 3 ways of doing the same thing instead of one way ? Can you please explain ?

    @gabrielfono844 2 роки тому +1

    it is very well explain
    since I have almost two years in coding
    I think begineer wont be able to understand.
    first . it is important to understand the "this " keyword
    this :reference the object that executing the current function.
    since the addTothis function will be an method of the object , then the this will reference that object.
    I hope begineer could understand it more
    please check out techsit video on 'this ' keyword first.
