1. Definition

The Date.getMilliseconds() method returns the milliseconds (from 0 to 999) of the specified date according to local time.

2. Syntax

dateObj.getMilliseconds();

Parameters

The Date.getMilliseconds() method does not take any parameters.

Return Value

The method returns an integer number, between 0 and 999, representing the milliseconds for the given date according to local time.

3. Examples

Let's look at some examples to understand how Date.getMilliseconds() works in TypeScript.

Example 1: Basic Usage

In this example, we use Date.getMilliseconds() to get the milliseconds from a specific date.

let date = new Date('2024-07-15T10:20:30.123Z');
let milliseconds = date.getMilliseconds();
console.log(milliseconds); // Output: 123

Example 2: Getting the Current Milliseconds

In this example, we use Date.getMilliseconds() to get the current milliseconds.

let now = new Date();
let currentMilliseconds = now.getMilliseconds();
console.log(currentMilliseconds); // Output: The current milliseconds, e.g., 456

Example 3: Using Date.getMilliseconds() with Different Times

In this example, we use Date.getMilliseconds() to get the milliseconds for different times.

let morning = new Date('2024-07-15T08:00:00.789');
let evening = new Date('2024-07-15T20:00:00.456');
console.log(morning.getMilliseconds()); // Output: 789
console.log(evening.getMilliseconds()); // Output: 456

Example 4: Using Date.getMilliseconds() with a Date Object

In this example, we use Date.getMilliseconds() with a date object created from the current date and time.

let date = new Date();
let milliseconds = date.getMilliseconds();
console.log(milliseconds); // Output: The current milliseconds

Example 5: Using Date.getMilliseconds() with Past and Future Dates

In this example, we use Date.getMilliseconds() to get the milliseconds for past and future dates.

let pastDate = new Date('2000-01-01T12:34:56.789');
let futureDate = new Date('2050-05-20T23:45:00.012');
console.log(pastDate.getMilliseconds()); // Output: 789
console.log(futureDate.getMilliseconds()); // Output: 12

Example 6: Using Date.getMilliseconds() in Different Time Zones

In this example, we use Date.getMilliseconds() to get the milliseconds for a date object in different time zones.

let date = new Date('2024-07-15T10:20:30.123Z');
let millisecondsUTC = date.getUTCMilliseconds();
let millisecondsLocal = date.getMilliseconds();
console.log(millisecondsUTC);   // Output: 123
console.log(millisecondsLocal); // Output: 123 (same for UTC and local as milliseconds are not affected by time zones)

4. Conclusion

In this chapter, we explored the Date.getMilliseconds() method in TypeScript, which is used to return the milliseconds (from 0 to 999) of the specified date according to local time. We covered its definition, syntax, parameters, return value, and provided several examples to demonstrate its usage. Understanding how to use Date.getMilliseconds() effectively can help in various scenarios where extracting the milliseconds from a date object is required.
