there I apply two regular expression to javascript string:
url.replace(/(^https?\:\/\/)?(www\.)?/i, '').replace(/\/$/, '')
how can I combine them into one replace
function?
Since the replacement is the same, you can use alternation to match/replace "this" or "that":
let url = 'http://www.example.com/'; console.log(url.replace(/^(?:https?\\:\\/\\/)?(?:www\\.)?|\\/$/gi, ''));
