_.bind(func, thisArg, [partials])

sourcenpm package

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.

Since

0.1.0

Arguments

• func (Function): The function to bind.
• thisArg (*): The this binding of func.
• [partials] (…*): The arguments to be partially applied.

Returns

  return greeting + ' ' + this.user + punctuation;
}
 
var object = { 'user': 'fred' };
 
var bound = _.bind(greet, object, 'hi');
bound('!');
// => 'hi fred!'
 
// Bound with placeholders.
