Converting a String to a Character Array in JavaScript
In JavaScript, obtaining a character array from a string is a straightforward process. To achieve this, the following steps can be taken:
Solution:
The simplest method to convert a string into a character array is by splitting it using an empty string. This is exemplified in the code below:
var output = "Hello world!".split('');
console.log(output);
When executed, the output would be:
[ 'H', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd', '!' ]
However, it's crucial to note that this approach may not be entirely Unicode compliant. For instance, splitting the string "I?U" with the empty string would result in the array ["I", "?", "?", "u"], leading to potential issues.
Alternative Approaches:
For Unicode-compliant methods, you can explore:
- Using the Array.from() method with a spread operator: [...string].
- Using the String.prototype.charCodeAt() method to get character codes and then converting them to a character array.

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.
