## 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 pure vanilla JavaScript version of this project, if you are looking for the npm-version, check here.
### 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.
### Example
```js
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! 🙌
