How Can I Split a JavaScript String Using Multiple Separators?

Splitting a String with Multiple Separators in JavaScript

To split a string using multiple separators in JavaScript, you can utilize the split() function with a regular expression (regexp) as its parameter.

To achieve this, construct a regexp that matches your desired separators. For instance, to split on both commas , and spaces , use /[s,] /. The ' ' quantifier ensures that one or more occurrences of the separators are matched.

Here's an example:

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

This will result in the string being split into an array of substrings: ["Hello", "awesome", "world!"].

Alternatively, if you want to obtain the last element of the split array, you can access it using the length property minus 1:

let bits = "Hello awesome, world!".split(/[\s,]+/)
let bit = bits[bits.length - 1]

This will assign the string "world!" to the variable bit.

In cases where the specified pattern does not match in the string, the split() function will return the original string. For example:

let bits = "Hello awesome, world!".split(/foo/)

The resulting array will contain only the original string: ["Hello awesome, world!"].
