Call function in javascript gives error

 

This question already has an answer here:

  • Javascript call() & apply() vs bind()? 17 answers

    • apply requires an array of parameter, you should use it as 

    saymyName.apply(o, ['hello there']);

    or else you could use call 

    saymyName.call(o, 'hello there');

    Use call instead of apply, as apply needs the second parameter to be an Array–like object.

    Use apply when an array of values needs to be sent as parameters to the called function (eg to pass all the arguments of the currently executing function using the arguments object).

    Demo 

    var o = {
  name: 'i am object',
  age: 22
};

function saymyName(arguentToFunc) {

  console.log('my name is ' + this.name + 'and thw argument  passed is ' + arguentToFunc);
}

saymyName.call(o, 'hello there');
