method:
1 2 3 4
let string = " This is a sample string "; string = string.trim();
2. Convert the string to lowercase using thetoLowerCase()
method:
1 2 3
string = string.toLowerCase();
3. Replace any special characters, punctuation, or whitespace with dashes using a regular expression and thereplace()
method:

string = string.replace(/[\s~`!@#$%^&*()+=,.<>?;:'"[\]{}|\\]/g, '-');
4. Remove consecutive dashes and replace them with a single dash using another regular expression and thereplace()
method:

string = string.replace(/-+/g, '-');
5. Remove any remaining non-alphanumeric characters using a regular expression and thereplace()
