How to Split a JavaScript String Using Multiple Separators?

Splitting Strings with Multiple Separators in JavaScript

Q: How can I split a string in JavaScript based on multiple separators, such as commas and spaces?

A: While the split() function traditionally only accepts one separator, you can overcome this limitation by utilizing a regular expression as the parameter:

"Hello awesome, world!".split(/[\s,]+/)
Output: ["Hello", "awesome", "world!"]

The regular expression [/s,] / matches both spaces and commas, allowing you to split the string accordingly.

Retrieving the Last Element

You can obtain the last element of the resulting array by subtracting 1 from its length:

const bits = "Hello awesome, world!".split(/[\s,]+/);
const lastBit = bits[bits.length - 1];
Output: "world!"

Handling Non-Matching Patterns

If the pattern does not match any separators in the string, the split() function will return a single element array containing the original string:

const noMatchBits = "Hello awesome, world!".split(/foo/);
const noMatchLastBit = noMatchBits[noMatchBits.length - 1];
Output: "Hello awesome, world!"
