Question

while I was reading a javascript book, I read the following sentence.

“The call object is initialized with a property named arguments that refers to the Arguments object for the function”

am I allow to output the structure (or values?) of a call object in javascript using console.log or alert() method??

when people say ‘a call object’, is it a concept or an object?

Answer 1

I believe they are referring to the object calling the method/function.

This can be referenced by the this keyword

<a onclick="foo()">click me</a>

function foo(){
  this.style.color='#cc0000';
  alert(arguments.length);
}

This code would change the text color of the anchor to ‘#cc0000’ and alert 0.
