Remove Parentheses From String Using JavaScript

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

var someString = "(This is )a (string with parentheses)";

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

console.log(someString);

#Output:
This is a string with parentheses

Since parentheses 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 left parenthesis. Using the regular expression /\(/g makes it so we replace ALL instances of left parenthesis in the string.

If we wanted to remove the parentheses with just one code of line, we could use the following regex expression.

var someString = "(This is )a (string with parentheses)";

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

console.log(someString);

#Output:
This is a string with parentheses

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. Parentheses can be troubling characters to deal with in string variables.

We can easily remove parentheses from a string in JavaScript.

The easiest way to get rid of parentheses 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 parentheses, we pass the parenthesis (“\(“) character as the first argument, and an empty string as the second argument.

Below are some examples of how you can remove parentheses from strings in JavaScript using the replace() function.

var someString = "(This is )a (string with parentheses)";

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

console.log(someString);

#Output:
This is a string with parentheses
