(static) bind(fn, thisArg, …varArgsopt) → {boundFunction}

The bind() function creates a new function (a bound function) with the same function body (internal call property in ECMAScript 5 terms) as the function it is being called on (the bound function's target function) with the this value bound to thisArg, which cannot be overridden.

Parameters:

Name	Type	Attributes	Description
`fn`	bindTargetFunction
`thisArg`	*		the this argument to be bound to the new function
`varArgs`	*	<optional> <repeatable>	any arguments to be bound to the new function.
