Temporal.Duration.prototype.abs()

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The abs() method of Temporal.Duration instances returns a new Temporal.Duration object with the absolute value of this duration (all fields have the same magnitude, but sign becomes positive).

Syntax

js
abs()

Parameters

None.

Return value

A new Temporal.Duration object with the absolute value of this duration, which is either the same as this duration if it is already positive, or its negation if it is negative.

Examples

Using abs()

js
const d1 = Temporal.Duration.from({ hours: 1, minutes: 30 });
const d2 = Temporal.Duration.from({ hours: -1, minutes: -30 });

console.log(d1.abs().toString()); // "PT1H30M"
console.log(d2.abs().toString()); // "PT1H30M"
