How to split a string into an array of single characters?

Converting Strings into Individual Character Arrays

Original Question: How can I divide a string into an array of strings, each containing only one character?

Explanation: Breaking a string down into individual characters can be achieved using the split method. However, it is essential to use a regular expression to ensure that the characters are separated correctly.

Solution:

Utilizing the regular expression (?!^), you can separate the characters without introducing extra characters or empty strings into the array. Here's the code snippet:

"cat".split("(?!^)")
Copy after login

Output:

Splitting the string "cat" using this method produces the desired array:

["c", "a", "t"]
Copy after login

By applying this solution, you can conveniently convert strings into arrays of strings, each element representing a single character.
