|
Helper functions around Function call/apply/bind, for use in `call-bind`. |
|
|
|
The only packages that should likely ever use this package directly are `call-bind` and `get-intrinsic`. |
|
Please use `call-bind` unless you have a very good reason not to. |
|
|
|
## Getting started |
|
|
|
```sh |
|
npm install --save call-bind-apply-helpers |
|
``` |
|
|
|
## Usage/Examples |
|
|
|
```js |
|
const assert = require('assert'); |
|
const callBindBasic = require('call-bind-apply-helpers'); |
|
|
|
function f(a, b) { |
|
assert.equal(this, 1); |
|
assert.equal(a, 2); |
|
assert.equal(b, 3); |
|
assert.equal(arguments.length, 2); |
|
} |
|
|
|
const fBound = callBindBasic([f, 1]); |
|
|
|
delete Function.prototype.call; |
|
delete Function.prototype.bind; |
|
|
|
fBound(2, 3); |
|
``` |
|
|
|
