const ipv6="([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+)";
const regex = new RegExp(ipv6);
const result = SAMPLE_STRING.match(regex);
console.log(result);run code result is
SyntaxError: Invalid regular expression: /([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+):([a-zA-Z0-9]{1,4}+)/: Nothing to repeatThe 'ipv6' works with a regex-compiler, but not with javascript.
