Jan 03, 2025 am 07:31 AMFormatting Dates in JavaScript: Dive into the Documentation
JavaScript's Date() function offers a remarkable flexibility in accepting dates in multiple formats, leaving many developers wondering about its comprehensive documentation. This article delves into the nuances of date formatting in JavaScript, providing insights into the available resources.
Converting Strings to Dates
The article highlights the Date() function's ability to interpret dates in various formats without the need for explicit documentation. Examples such as "25 Dec, 1995 23:15:00" and "20 09 2006,12:52:39" illustrate this versatility.
Converting Dates to Strings
Initially, it was believed that JavaScript lacked a built-in API for converting date objects into strings. However, the article introduces the toString() method as a means to achieve this formatting. Examples such as "d1.toString('yyyy-MM-dd')" and "d1.toString('dddd, MMMM ,yyyy')" demonstrate the syntax.
The Need for Documentation
Despite the availability of these formatting techniques, the article emphasizes the lack of official documentation outlining the supported date format specifiers. Without such resources, developers may struggle to navigate the formatting process effectively.
Suggested Resources
To bridge this gap, the article recommends two online resources: "10 Ways to Format Time and Date Using JavaScript" and "Working with Dates." Both of these provide valuable guidance on date formatting and help developers create custom string representations of their dates.
Combining Methods
The article further suggests a practical approach to formatting dates by combining the getDate(), getMonth(), and getFullYear() methods. An example is provided, where the current date is formatted as "mm-dd-yyyy" using these methods.
Conclusion
Although JavaScript offers robust date formatting capabilities, the lack of comprehensive documentation can hinder developers' understanding. This article serves as a starting point for exploring the available options and provides valuable resources to guide developers in their date formatting endeavors.

The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.

If JavaScript applications load slowly and have poor performance, the problem is that the payload is too large. Solutions include: 1. Use code splitting (CodeSplitting), split the large bundle into multiple small files through React.lazy() or build tools, and load it as needed to reduce the first download; 2. Remove unused code (TreeShaking), use the ES6 module mechanism to clear "dead code" to ensure that the introduced libraries support this feature; 3. Compress and merge resource files, enable Gzip/Brotli and Terser to compress JS, reasonably merge files and optimize static resources; 4. Replace heavy-duty dependencies and choose lightweight libraries such as day.js and fetch
