fast-bind

The fastest Function#bind I could find.

Function#bind (native) x 709,955 ops/sec ±1.79% (84 runs sampled)
Function#bind (slice) x 2,610,293 ops/sec ±1.43% (99 runs sampled)
Function#bind (concat) x 2,622,574 ops/sec ±0.79% (101 runs sampled)
Function#bind (loop) x 2,952,311 ops/sec ±1.63% (95 runs sampled)
Fastest is Function#bind (loop)
4.16x as fast as Function#bind (native)

Installation

npm install fast-bind

API

Function.prototype.bind = require('fast-bind')

Faster

The previous version did not handle using the bound function as a constructor. This requires an instanceof check, and slows everything down a bunch.

Function#bind (native) x 803,410 ops/sec ±2.35% (79 runs sampled)
Function#bind (slice) x 4,771,960 ops/sec ±0.95% (99 runs sampled)
Function#bind (concat) x 3,838,614 ops/sec ±1.41% (95 runs sampled)
Function#bind (loop) x 6,440,278 ops/sec ±0.69% (97 runs sampled)
Fastest is Function#bind (loop)
8.02x as fast as Function#bind (native)
