Temporal.Duration.prototype.microseconds

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 microseconds accessor property of Temporal.Duration instances returns an integer representing the number of microseconds in the duration.

Unless the duration is balanced, you cannot assume the range of this value, but you can know its sign by checking the duration's sign property. If it is balanced to a unit above microseconds, the microseconds absolute value will be between 0 and 999, inclusive.

The set accessor of microseconds is undefined. You cannot change this property directly. Use the with() method to create a new Temporal.Duration object with the desired new value.

Examples

Using microseconds

const d1 = Temporal.Duration.from({ milliseconds: 1, microseconds: 500 });
const d2 = Temporal.Duration.from({ milliseconds: -1, microseconds: -500 });
const d3 = Temporal.Duration.from({ milliseconds: 1 });
const d4 = Temporal.Duration.from({ microseconds: 1000 });

console.log(d1.microseconds); // 500
console.log(d2.microseconds); // -500
console.log(d3.microseconds); // 0
console.log(d4.microseconds); // 1000

// Balance d4
const d4Balanced = d4.round({ largestUnit: "milliseconds" });
console.log(d4Balanced.microseconds); // 0
console.log(d4Balanced.milliseconds); // 1
