#How to get current date data in JavaScript

Getting current date data is a common task in JavaScript. Several methods can be used to achieve this:

Date Objects

You can use Date objects to represent specific dates and times. To get the current date, you can use the new Date() constructor.

<code class="js">const now = new Date();</code>

Date The object provides a variety of methods to access date and time information, for example:

• getDay(): Get the day of the week Number (0-6, 0 represents Sunday)
• getDate(): Get the date (1-31)
• getMonth(): Get the month (0-11, where 0 represents January)
• getFullYear(): Get the year

For example:

<code class="js">console.log(`当前星期：${now.getDay() + 1}`); // 输出：当前星期几
console.log(`当前日期：${now.getDate()}`); // 输出：当前日期
console.log(`当前月份：${now.getMonth() + 1}`); // 输出：当前月份
console.log(`当前年份：${now.getFullYear()}`); // 输出：当前年份</code>

Date.now()

Another way to get the current date data is to use the Date.now() method. This method returns the number of milliseconds since January 1, 1970 00:00:00 UTC.

<code class="js">const timestamp = Date.now();</code>

This timestamp can be used to calculate relative times or compare with other timestamps.

Library

You can also use JavaScript libraries to obtain date data, for example:

• Moment.js: A tool for manipulating dates Popular library that provides a variety of convenient methods and formatting options.
• Date-fns: Another popular date library that provides some useful functions such as adding, subtracting and comparing dates.
