Demo

Usage

import { createGenericProjection } from '@reause/math'

const projector = createGenericProjection(
  [0, 10],
  ['cold', 'hot'],
  (value, fromDomain, toDomain) => (value > (fromDomain[0] + fromDomain[1]) / 2 ? toDomain[1] : toDomain[0]),
)

projector(8) // 'hot'

Type Declarations

export type UseProjection<F, T> = (input: F) => T

export type ProjectorFunction<F, T> = (input: F, from: readonly [
    F,
    F
], to: readonly [
    T,
    T
]) => T

export function createGenericProjection<F = number, T = number>(fromDomain: readonly [
    F,
    F
], toDomain: readonly [
    T,
    T
], projector: ProjectorFunction<F, T>): UseProjection<F, T>

export function useProjection(input: number, fromDomain: readonly [
    number,
    number
], toDomain: readonly [
    number,
    number
], projector?: ProjectorFunction<number, number>): number
