extarray

Extended array functionality. Work in progress, but stable. Eventually there will be more functions and classes to use.

Added functions for Array and Array.prototype

Check if an array only has values of allowed type(s)

• Array.isAllType(array,type | types) Push value if it doesn't exist or remove it if it does
• Array.prototype.add(value)
• Array.prototype.remove(value)
• Array.prototype.toggle(value) Do arithmetic with vectors
• Array.prototype.vectorAdd(otherArray)
• Array.prototype.vectorMultiply(otherArray)

Note: vectorAdd works with strings as well (although strings like "1" + "2" will be added into "12"). vectorMultiply works with strings only if they can be parsed into numbers, and then it multiplies them normally. I recommend only using numbers with both, but you do you. Also note that vectorAdd and vectorMultiply return a new array rather than mutating the array. This means if you want to set an array to itself plus another one you'll have to do something along the lines of array = array.vectorAdd(otherArray) but you can also use both functions to create new arrays without fear of messing up your data.

Usage

If you only want to use the above functions and don't need the extra classes, it's really simple:

import 'extarray'
let array = [0,1,2];
Array.isAllType(array,"number") // > true
array.add(3) // > array = [0,1,2,3]
array.vectorMultiply([0,2,4,6]) // > [0,2,8,18]

Important note! This only works with static imports. That means this doesn't work in commonJS's import('extarray') function. Your package has to be a module, too. In your package.json, you can include "type": "module", and that should fix it!

New Classes

So far, I've only added Vector2 and Vector3. Both are just arrays of numbers at that specific length.

import {Vector2} from 'extarray'
let position = new Vector2(0,1) // > Vector2 [0,1]
Array.isArray(position) // > true
Vector2.isVector2(position) // > true
