## 🎉 UArray 🙌



	






Provides `UArray`, an `Array` type that supports negative indices/indexes, just wrap your _regular_ JavaScript array with `UArray()` or pass the elements directly to `UArray()` and you are all set! 🎉🙌




 ⚠ Uses the built-in Proxy object, check browser compatibility on the Can I Use website.








📢 This is the npm version of this project, if you are looking for the vanilla JavaScript version, check this.






### Usage




ℹ Works like negative indices in other languages, e.g. **-1** picks that **last** element, **-2,** the **second to last**, etc.




✨ Since `v.1.1.0` the function signature has been changed and now it supports 2 different ways of action. You can now pass a single parameter of type `Array` or multiple parameters of any primitive type.




Install it first by doing,

```shell

npm i "@igor.dvlpr/uarray"

```




and then use it,




```js

const UArray = require('@igor.dvlpr/uarray')

const food = UArray(['🍟', '🌭', '🍿', '🥙', '🥓']) // array passed

const objects = UArray('🎈', '🎩', '⚽', '🥇', '🎯') // no array passed, just direct values

console.log(food[-1]) // prints '🥓'

console.log(food[-3]) // prints '🍿'

console.log(objects[-1]) // prints '🎯'

console.log(objects[-3]) // prints '⚽'

```






🎉 Happy coding! 🙌
