Question

What is the use of bind() in JavaScript?

Answer 1

The bind function creates a new function with the same function body as the function it is calling .It is called with the this argument .why we use bind fun. : when every time a new instance is created and we have to use first initial instance then we use bind fun.We can't override the bind fun.simply it stores the initial object of the class.

setInterval(this.animate_to.bind(this), 1000/this.difference);
