  You can use the replace function in JavaScript along with regular expressions to replace invalid characters in a cryptocurrency address. Here's an example code snippet: const address = '1AbCdeFgH123'; const cleanedAddress = address.replace(/[^a-zA-Z0-9]/g, ''); In this code, the regular expression /[^a-zA-Z0-9]/g matches any character that is not a letter or a digit. The replace function replaces all occurrences of these invalid characters with an empty string, effectively removing them from the address. The cleanedAddress variable will now contain the cryptocurrency address with all the invalid characters removed. Remember to adjust the regular expression pattern to match the specific invalid characters you want to remove from the address.
