bind

Bind this-object, and optional prefix arguments to a function.

Similar: bind, attach.

function bind(x, ths, ...prefix)
// x:      a function
// ths:    this object to bind
// prefix: prefix arguments

const xasyncfn = require('extra-async-function');


var array  = [1];
var fn = xasyncfn.bind(Array.prototype.push, array);
fn(2, 3, 4);  // push(2, 3, 4)
array;
// → [1, 2, 3, 4]

var array  = [1, 2, 3, 4];
var fn = xasyncfn.bind(Array.prototype.splice, array, 1);
fn(2);  // splice(1, 2)
array;
// → [1, 4]
