normalize ​

Problem ​

You need to map a value from an arbitrary range into 0–1 — for example computing progress percentages or scaling data for a chart.

Solution ​

Use normalize(value, min, max) to return a [0, 1] proportion.

ts
import { normalize } from '@vielzeug/arsenal';

normalize(75, 0, 100); // 0.75
normalize(0, 0, 100); // 0
normalize(50, 25, 75); // 0.5

Pitfalls ​

  • When min === max, returns NaN (division by zero).
  • Does not clamp output — values outside [min, max] produce results outside [0, 1].
