babel-plugin-array-includes

> Replaces arr.includes(val) with arr.indexOf(val) >= 0.

Thanks to @sebmck for the help.

Example

In

``javascript
[1, 2, 3, 5, 8, 13].includes(4);
`

Out

`javascript
"use strict";

[1, 2, 3, 5, 8, 13].indexOf(4) >= 0;
`

Pitfalls

This doesn't work:

In

`js
function foo(arr) {
return arr.includes('foo');
}
`

Out

`js
function foo(arr) {
return arr.includes('foo'); // still includes
}
`

Installation

`sh
$ npm install babel-plugin-array-includes
`

Usage

$3

.babelrc

`json
{
"plugins": ["array-includes"]
}
`

$3

`sh
$ babel --plugins array-includes script.js
`

$3

`javascript
require("babel-core").transform("code", {
plugins: ["array-includes"]
});
