The purpose of filter()
is to remove currentGroup
matching with URLs from the array. It doesn’t matter there is numbers after Malappuram/123456/12
or not. Is there any best way to do it in ES6 ?

const initialLinks = [

const urls = R.uniq(initialLinks)
.filter(filterOwnLinks)
.map(normalizeTme);
console.log(initialLinks);
console.log(urls);

You can use
URL
api to parse url, and take the pathname from parse url object, and check if starts withcurrentGroup
You could
test
with a simple regular expression within theArray.prototype.filter
callback:
