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.
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.
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! 🙌
