REGEX ONLY
I exclusively need Javascript regex code to convert URLs like
https://hello.romeo-juliet.fr
https://hello.romeojuliet.co.uk
https://hello.romeo-jul-iet.fr
https://hello.romeo-juliet.com
into this string romeojuliet
Basically want to get the alphabetic domain name with removing all other characters and https://, com/co.uk/fr etc Top Level Domains
Would be helpful if done using JS replace.
I tried till here
let url="https://hello.romeo-juliet.fr";
const test=url.replace(/(^\w+:|^)\/\/(\w+.)/, '');
console.log(test);A non regex solution:
Get the host of the URL (by parsing the string with the URL() constructor and getting its host property), split by a period and get the second item in the resulting array, then remove all occurences of -:
let url="https://hello.romeo-juliet.fr";
const test = new URL(url).host.split(".")[1].replaceAll("-", '');
console.log(test);You can use it with no regex as the following:
let url="https://hello.romeo-juliet.fr";
url.substring(url.indexOf(".")+1, url.lastIndexOf("."));
// result: romeo-juliet
I hope this answers your question
