JavaScript method setUTCFulYear() to set the year according to Universal Time (UTC)
Definition and Usage
The setUTCFullYear() method is used to set the year according to Universal Time (UTC).
Syntax
dateObject.setUTCFullYear(year,month,day)
Parameters | Description |
year | Required. The value of the year field to set for the dateObject. This parameter should be the complete year with century value, such as 1999, not just the abbreviated year value, such as 99. |
month |
Optional. The value of the month field to set for the dateObject. Expressed using world time. This parameter is an integer between 0 ~ 11. |
day |
Optional. The value of the day field to be set for dateObject. Expressed using world time. This parameter is an integer between 1 ~ 31. |
Return value
Adjusted date expressed in milliseconds
Tips and comments:
Comments : This method is always used in conjunction with a Date object.
Tip: For more information about Universal Coordinated Time (UTC), please refer to Baidu Encyclopedia.
Example
Example 1
In this example, we will set the year to 1992 through the setUTCFulYear() method:
<script type="text/javascript"> var d = new Date() d.setUTCFullYear(1992) document.write(d) </script>
Output:
Sat Nov 07 1992 14:21:20 GMT+0800 (中国标准时间)
Example 2
In this example, I will set the date to November 3, 1992 through the setUTCFulYear() method:
<script type="text/javascript"> var d = new Date() d.setUTCFullYear(1992,10,3) document.write(d) </script>
Output:
Tue Nov 03 1992 14:21:20 GMT+0800 (中国标准时间)
If the monthValue and dayValue parameters are not specified, the values returned from the getMonth and getDate methods are used. If the specified parameters are outside the expected range, call setUTCFullYear to try to update other parameters and the corresponding date information of the Date object. For example, if you specify 15 for monthValue, the year is in increments of 1 (year + 1), and 3 is used to represent the month.
Example:
<html> <head> <title>JavaScript setUTCFullYear Method</title> </head> <body> <script type="text/javascript"> var dt = new Date( "Aug 28, 2008 23:30:00" ); dt.setUTCFullYear( 2006 ); document.write( dt ); </script> </body> </html>
This will produce the following results:
Mon Aug 28 23:30:00 UTC+0530 2006

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.
