MDN / Temporal.Duration.prototype.milliseconds

The milliseconds accessor property of [ The **milliseconds`** accessor property of {{jsxref(“Temporal/Duration”)}} instances returns an integer representing the number of milliseconds 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 milliseconds, the milliseconds absolute value will be between 0 and 999, inclusive/

The set accessor of milliseconds is undefined/ You cannot change this property directly/ Use the {{jsxref(“Temporal/Duration/with”, “with()”)}} method to create a new Temporal/Duration object with the desired new value/

Examples

Using milliseconds

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

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

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