# How To Replace All Forward Slashes In A JavaScript String

If you don’t know how to replace all forward slashes in a Javascript string. Let’s read this article to understand how to do it.

## Replace all forward slashes in a Javascript string

### Use replace() method

By default, the replace method will only replace the character when it first appears in the original string. However, using replace() method in combination with a regular expression with the specified glocal flag, we can completely replace all characters in the original Javascript string.

For example, suppose we want to replace all forward slashes with a colon. In that case, we will use the replace function with a regular expression /\//g because the forward slash (/) is a unique character in regular expressions, a backslash (\) is needed for it to be escaped.

Code sample:

let string = "Learn/Share/IT";

// Use the replace function to replace all the forward slashes (/) with hyphens (-)
let myStr = string.replace(/\//g, '-');

console.log(myStr);

Output

Learn-Share-IT

### Use replaceAll() method

A simpler way to replace all forward slashes without a regular expression is to use the replaceAll() method.

Code sample:

let string = "Learn/Share/IT";

// Use the replaceAll function to replace all the forward slashes (/) with dots (.)
let myStr = string.replaceAll('/', '.');

console.log(myStr);

Output

Learn.Share.IT

With the replaceAll() method, we only need to pass it a first parameter which is the string containing a forward slash, and the second parameter is the replacement string. It will replace all forward slashes with the replacement string.

### Use split() and join() method

An excellent idea to replace all forward slashes is to split the given string by the forward slash and then join the string to the desired character.

If you want to split a string into an array of strings based on slashes, use the split() method. Then to combine an array of strings by a specified character, we use the join() method.

Code sample:

let string = "Learn/Share/IT";

// Split the string into an array and join each element of the array together into a new string
let myStr = string.split('/').join('');

console.log(myStr);

Output

LearnShareIT

## Summary

Above, I have shown you how to replace all forward slashes in a Javascript string by the replace(), replaceAll(), split(), and join() methods. I hope they are helpful to you, you should choose the best option for your case. To better understand the lesson’s content, practice rewriting today’s examples.
