JavaScript: Extract Number from String in 80 characters

Do you need to extract numbers from a string provided by a user input in HTML form fields? Look no further! JavaScript, with the help of regular expressions, can easily extract those numbers for you!

To extract a number from a string using regular expressions, you can utilize \d+ as shown below:

            const string = "x12345david";
            const [match] = string.match(/(\d+/);
            match; // 12345
        

Regular expressions offer powerful operations in JavaScript, and extracting numbers is just one of them. You can convert the extracted number to a Number type by wrapping it in the Number() function.
