Hi Friends 👋,

Welcome To Infinitbility! ❤️

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

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 and space using replace() method.

const regex = /[ `[email protected]#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/g;

var str = "12 3&&9 04";

// + unary plus oprator it's the fastest way to convert a string to a number
+str.replace(regex, '');
// 👇️ Output
//  123904

Today, I’m going to show you How do I remove special characters and spaces from numbers in javascript, as above mentioned here, I’m going to use the replace() method with /[ `[email protected]#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?~]/g regex to delete special characters and space from a string and then convert it to number.
