How to Convert a JavaScript String to a Character Array (and Handle Unicode)?

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.
