Quick start

A usage example from the call-bind README.

jsFull README ↗
const assert = require('assert');
const callBind = require('call-bind');
const callBound = require('call-bind/callBound');

function f(a, b) {
	assert.equal(this, 1);
	assert.equal(a, 2);
	assert.equal(b, 3);
	assert.equal(arguments.length, 2);
}

const fBound = callBind(f);

const slice = callBound('Array.prototype.slice');
