|
|
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);
|
|
```
|
|
|
|
