How to move the digits of a string with digits and letters to the beginning of the string in JavaScript

Answer 1

function moveDigitsToFront(str) {
    // Separate digits and non-digits using regex
    const digits = str.replace(/\D/g, ""); // Extract digits
    const nonDigits = str.replace(/\d/g, ""); // Extract non-digits

    // Combine digits and non-digits
    return digits + nonDigits;
}

const str = "d2c54be3a1";
const output = moveDigitsToFront(str);

console.log(output);
