Function bind

bind<T>(func: T, thisArg?: any, ...partials: any[]): T
Creates a function that invokes func with the this binding of thisArg and partials prepended to the arguments it receives.

The bind.placeholder value, which defaults to _ in monolithic builds, may be used as a placeholder for partially applied arguments.

Note: Unlike native Function#bind, this method doesn't set the "length" property of bound functions.
Type Parameters
- T
Parameters
- func: T
  The function to bind.
- OptionalthisArg: any
  The this binding of func.
- ...partials: any[]
  The arguments to be partially applied.
Returns T
Returns the new bound function.
Since
5.3.0
Example
```
function greet(greeting, punctuation) {
  return greeting + ' ' + this.user + punctuation;
}

var object = { 'user': 'fred' };

var bound = bind(greet, object, 'hi');
bound('!');
// => 'hi fred!'

// Bound with placeholders.
var bound = bind(greet, object, _, '!');
bound('hi');
// => 'hi fred!'
```
