how to remove special characters and space from string in javascript?

Hi Friends 👋,

Welcome To Infinitbility! ❤️

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

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 the pattern is a string, only the first occurrence will be replaced.

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

Copy

2
3var str = "Hi Frinds & Welcome to infinitbility";
4
5str.replace(regex, '');
6// 👇️ Output
7//   "HiFrindsWelcometoinfinitbility"
