Second bind

الأهمية: 5

Can we change this by additional binding?

What will be the output?

function f() {
  alert(this.name);
}

f = f.bind( {name: "John"} ).bind( {name: "Ann" } );

f();

The answer: John.

function f() {
  alert(this.name);
}

f = f.bind( {name: "John"} ).bind( {name: "Pete"} );

f(); // John

The exotic bound function object returned by f.bind(...) remembers the context (and arguments if provided) only at creation time.

A function cannot be re-bound.
