function generateIdFromString(input) {
  return input
    .toLowerCase()               // Convert the string to lowercase
    .replace(/[^a-z0-9\s-]/g, '') // Remove all non-alphanumeric characters except spaces and hyphens
    .trim()                      // Remove leading and trailing spaces
    .replace(/\s+/g, '-')        // Replace spaces with hyphens

const originalString = "Hello World! This is a Test.";
const idValue = generateIdFromString(originalString);
console.log(idValue); // Output: "hello-world-this-is-a-test"
