how to remove special characters from string in react js?

Hi Friends 👋,

Welcome To Infinitbility! ❤️

To remove special characters from string in react js, just use replace() method with /[ `[email protected]#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/g regex then it will return new string without special characters.

The replace() method returns a new string with some or all matches of a pattern replaced by a replacement. The pattern can be a string or a RegExp, and the replacement can be a string or a function called for each match. If pattern is a string, only the first occurrence will be replaced.

Let’s take an example to remove special characters using replace() method.

1const regex = /[ `[email protected]#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/g;
2
3var str = "(in)[fi]ni`tb*il#it%y";
4
5str.replace(regex, '');
6// 👇️ Output
7//  "infinitbility"
