Using function.bind to Create New Functions

Syntax

bind(thisArg)
bind(thisArg, arg1)
bind(thisArg, arg1, arg2)
bind(thisArg, arg1, arg2, /* …, */ argN)

Parameters

thisArg

The value to be passed as the this parameter to the target function func when the bound function is called. If the function is not in strict mode, null and undefined will be replaced with the global object, and primitive values will be converted to objects. The value is ignored if the bound function is constructed using the new operator.

arg1, …, argN Optional

Arguments to prepend to arguments provided to the bound function when invoking func.

Return value

A copy of the given function with the specified this value, and initial arguments (if provided).
