Using JavaScript to Remove Backslash From a String

In JavaScript, to remove a backslash from a string, the easiest way is to use the JavaScript String replace() method.

var someString = "\\This is \\a \\string with backslashes";

someString = someString.replace(/\\/g, '');

console.log(someString);

#Output:
This is a string with backslashes

Since backslashes are special characters we must escape them by putting a backslash in front of them, as seen in the code above.

Notice in the replace method above, that instead of using .replace("\\", '') we use replace(/\\/g, ''). If we used the expression "\\" in the replace function, it only replace the FIRST instance of a backslash. Using the regular expression /\\/g makes it so we replace ALL instances of a backslash in the string.

When using string variables in JavaScript, we can easily perform string manipulation to change the value of the string variables.

One such manipulation is to remove characters from a string variable. Backslashes can be troubling characters to deal with in string variables.

We can easily remove backslashes from a string in JavaScript.

The easiest way to get rid of a backslash in a string using JavaScript is with the JavaScript String replace() function.

The replace() function takes two arguments: the substring we want to replace, and the replacement substring. In this case, to remove backslashes, we pass the backslash (“\\”) character as the first argument and an empty string as the second argument.

Below is our example again of how you can remove backslashes from strings in JavaScript using the replace() function.

var someString = "\\This is \\a \\string with backslashes";

someString = someString.replace(/\\/g, '');

console.log(someString);

#Output:
This is a string with backslashes
