Regular Expressions - Reuse Patterns Using Capture Groups - Free Code Camp

[JazzFanss]

I'm having a lot of trouble for regular expression because I feel the notation like .* + when combined with other notations is difficult to understand how things should be matched or repeated. Thank you for the insight when you should add ^ and + it clears up the cloud in my head a little

Thanks man. Great to see a different perspective when learning!

Dude you explained this in ~4 minutes and made more sense than the free code camp explanation. I'm probably a better visual learner.

[vizlodunken]

but on your code you added another 42 why instead of just dealing with the Regex only or is this also part of the challenge

[zinebakerkkaou]

Thank you so much for explaining that, I totally get it ☺

Thank you so much for your help Mr. Ian
let repeatNum = "42 42 42";
let reRegex = /^(\d+)\s\1\s\1$/;
let result = reRegex.test(repeatNum);
console.log(result);

I'm never going to get passed this problem.. nothing works

[derlynhernandez]

Why was their a second \s?
even though the first \s took care of it.
never mind, it only repeats the digit.
Either way, Thanks for explaining!

i want to split file for example 123VishalABC into 123, Vishal, ABC how to do that

For ppl who failed with /^(\d+)\s\1\s\1$/ getting: Your regex should not match the string 42\t42\t42. This works: /^(\d+) \1 \1$/ 🤕🙄

Hi! I do have a doubt and I hope you can help me:

let repeatStr = “row row row your boat”;

let repeatRegex = /(\w+) \1 \1/; // they refer to the substring twice

repeatStr.match(repeatRegex); // Returns [“row row row”, “row”]
//So over here shouldn’t that return [“row row row”, “row”, “row”]

So what is it that I´m missing this is the example that is RN on freecodecamp so could it be possible that is incorrect?
