Handling Large Numbers in JavaScript: Native BigInt vs. External Libraries
JavaScript lacks a built-in solution for handling large numbers, leaving developers with two primary options:
Option 1: External Libraries
Loading external libraries like the ones mentioned in the question is a common approach. However, this comes with potential drawbacks such as slower loading times and security concerns.
Option 2: Native BigInt (modern browsers only)
Since August 2019, Firefox and Chrome have supported the BigInt data type, providing a native solution for working with large numbers. This eliminates the need for external libraries:
const bigInt1 = 1111111111111111111111111111111n;
const bigInt2 = BigInt("1111111111111111111111111111111")
console.log((bigInt1 + bigInt2)+"")
Custom Implementations
Alternatively, developers can create their own BigInt implementations based on existing libraries like "javascript-biginteger" or "euler.html." However, this requires coding effort and validation to ensure accuracy and performance.
Java Bignum Libraries
In cases where JavaScript's native BigInt is insufficient, developers may consider calling into Java bignum libraries like apfloat. However, this approach involves potential cross-language interoperability challenges and the requirement for a Java runtime environment.

How to work with dates and times in js?
Jul 01, 2025 am 01:27 AM
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.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
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.
