I have completed the step but there is some of the wording the step I don’t understand. See the italics what does the writer mean by the result I am not sure.
"One last thing with this expression. You don’t actually need the match value from your capture group, so you can turn it into a non-capturing group. This will allow you to group the characters together without preserving the result.
To create a non-capturing group in a regular expression, you can add ?: after the opening parenthesis of a group. For instance, (?:a|b) will match either a or b, but it will not capture the result.
Update your regular expression to use a non-capturing group."
hi there,
please give us a link to the step you are working on so we can follow along with your question.
ah ok.
So the statement is saying this.
Since the original statement used a capturing group, but we didn’t actually use that captured (matched) data for anything, we can switch our expression to use a ‘non-capturing group’ instead.
It’s basically what you use if you have no plans to re-use the captured (matched) data.
I think I now get this enough. I suspect an example of reusing matched data will happen later in the course , then I will understand fully. Of course you likely know.
For clarity when I say course I mean more than the current program, despite the official wording.
tbh I don’t know if the course includes this because when I did it, it did not.
But you can easily see an example online.
google something like using capturing groups in javascript regex
The fact that among the moderators there are those that started as course learners is a positive sign of the running of freeCodeCamp.
