Convert UTC Epoch to Local Date: A Comprehensive Solution
The challenge of converting a UTC epoch to a local date arises when the default behavior of the Date() constructor assumes local epoch. This can lead to inaccuracies in date representation.
To address this issue, a more robust approach can be employed:
Solution:
- Initialize a Date object to the epoch (0):
var d = new Date(0);
- Convert the UTC epoch to seconds:
var utcSeconds = // Replace with your UTC epoch in seconds
- Set the UTC seconds using the Date object's setUTCSeconds method:
d.setUTCSeconds(utcSeconds);
This approach ensures that the resulting date, stored in the "d" variable, represents the specified UTC epoch in the local time zone.
Example:
Consider a UTC epoch of 1234567890:
var utcSeconds = 1234567890; var d = new Date(0); d.setUTCSeconds(utcSeconds);
The "d" variable will now hold the local date equivalent to this UTC epoch: Fri Feb 13 2009 18:31:30 GMT-0500 (EST).

Java and JavaScript are different programming languages, each suitable for different application scenarios. Java is used for large enterprise and mobile application development, while JavaScript is mainly used for web page development.

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
