How to Remove all Hyphens from a String in JavaScript

Remove all Hyphens from a String #

Use the replaceAll() method to remove all hyphens from a string, e.g. const hyphensRemoved = str.replaceAll('-', '');. The replaceAll method will remove all hyphens from the string by replacing them with empty strings.

Copied!
const str = '1-2-3';

const hyphensRemoved = str.replaceAll('-', '');
console.log(hyphensRemoved); // 👉️ 123

We passed the following arguments to the String.replaceAll method:

1. a substring we need to match in the string, in our case a hyphen -
2. a replacement string for each match

Alternatively, you can use the replace() method.

Use the String.replace() method to remove all hyphens from a string, e.g. const hyphensRemoved = str.replace(/-/g, '');. The replace() method will remove all hyphens from the string by replacing them with empty strings.

Copied!
const str = '1-2-3';

const hyphensRemoved = str.replace(/-/g, '');
console.log(hyphensRemoved); // 👉️ 123

We passed the following arguments to the String.replace method:

1. a regular expression to match in the string
2. a replacement for each match

We used the g (global) flag because we want to match all occurrences of a hyphen and not just the first occurrence.

To remove the hyphens from the string, we simply replace them with empty strings.
