API

outItem

Filter out an item from an array

const arr = [1, 2, 3, 4, 5]
const filtered = arr.filter(outItem(3))
console.log(filtered) // [1, 2, 4, 5]

compareBy

Sorts an array of objects by a property.

const arr = [
	{ name: 'John', age: 25 },
	{ name: 'Jane', age: 22 },
	{ name: 'Doe', age: 30 }
]
const sorted = arr.sort(compareBy('age'))
console.log(sorted)
// [
//  { name: 'Jane', age: 22 },
//  { name: 'John', age: 25 },
//  { name: 'Doe', age: 30 }
// ]

mapToUnit

Re-maps a number from one range to 0-1 and constrains the value.

const mapped = mapToUnit(50, 0, 100)
console.log(mapped) // 0.5

map

Re-maps a number from one range to another.

const mapped = map(50, 0, 100, 0, 200)
console.log(mapped) // 100

constrain

Constrains a value to not exceed a maximum and minimum value.

const constrained = constrain(150, 0, 100)
console.log(constrained) // 100
