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'); | ||
|
||
delete Function.prototype.call; | ||
delete Function.prototype.bind; | ||
|
||
fBound(1, 2, 3); | ||
|
||
assert.deepEqual(slice([1, 2, 3, 4], 1, -1), [2, 3]); | ||
