    Regular expressions are patterns used to match character combinations in strings. In JavaScript, regular expressions are also objects. Get started:

    This feature is about identifying capture groups via names. // Without named capture groups const re = /(\d{4})-(\d{2})-(\d{2})/; const match = re.exec('2021-03-04'); console.log(match[1]); // → 2021 (year) console.log(match[2]); // → 03 (month) console.log(match[3]); // → 04 (day) // With named capture groups 🔥 const re = /(?<year>\d{4})-(?<month>\d{2})-(?<day>\d{2})/; const match = re.exec('2021-03-04'); console.log(match.groups.year); // → 2021 console.log(match.groups.month); // → 03 console.log(match.groups.day); // → 04 // ... and with destructuring assignment 🔥🔥🔥 const [match, year, month, day] = re.exec('2021-03-04');
    Tip: You can name capture groups for Regular Expressions in JavaScript. Define a named capture in angle brackets <> and they get returned under .groups.

    ”MDN at the end” is the answer to everything. 😀 What’s your most recent “MDN” search?

    Replying to @millertchris @TheJackForge
    Hell I don’t even wait to ask for the MDN doc anymore...just Google whatever it is and put “MDN” at the end to save me time.
