partial

_.partial(func, partials) # Ⓢ [Ⓣ][1] Ⓝ

Creates a function that invokes func with partials prepended to the



arguments it receives. This method is like _.bind except it does not



alter the this binding.





The _.partial.placeholder value, which defaults to _ in monolithic



builds, may be used as a placeholder for partially applied arguments.





Note: This method doesn't set the "length" property of partially



applied functions.

Since​

0.2.0

Arguments​

  1. func (Function): The function to partially apply arguments to.
  2. partials (*|*[]): The arguments to be partially applied.

Returns​

(Function): Returns the new partially applied function.

Example​

function greet(greeting, name) {
  return greeting + ' ' + name;
}

var sayHelloTo = _.partial(greet, 'hello');
sayHelloTo('fred');
// => 'hello fred'

// Partially applied with placeholders.
var greetFred = _.partial(greet, [_, 'fred']);
greetFred('hi');
// => 'hi fred'
