> take any value, turn it to an array if it is not already one

## 📦 usage
```bash
yarn add to-arr
npm i to-arr --save
```

```js
const toArr = require('to-arr')
```

## 📘 examples

makes it very easy to loop over arguments without having to deal with checks

### safety

```js
function doSomethingCrazy(arg) {}
const allOpts = {includeEmpty: true}
const splitOpts = {split: '-'}
const loopData = (args) => toArr(args).forEach(doSomethingCrazy)
const loopAllData = (args) => toArr(args, allOpts).forEach(doSomethingCrazy)
const loopSplit = (args) => toArr(args, splitOpts).forEach(doSomethingCrazy)

// will loop an empty array, 0 iterations
loopData(null)

// will loop an array including null
loopAllData(null)

// loops 3 strings
const arrOfStrs = toArr('string1-string2-string3')
```


### strings

```js
const arrOfStrs = toArr('string1,string2,string3')
const arrOfStr = toArr('just one array entry')
```

### objects & arrays

```js
const obj = {luke: 'use the strings, forget me'}
const keys = toArr(obj, {keys: true})

const objs = toArr(obj)
const objs = toArr(objs)
console.assert(objs === objs)
```
