Match Single Characters Not Specified lesson

Is it me or the lesson is badly written when it asks to match all characters that are not a number?

Your code so far


let quoteSample = "3 blind mice.";
let myRegex = /[^aeiou0-9]/gi; // Change this line
let result = quoteSample.match(myRegex); // Change this line

The instructions I’m seeing for this challenge say:

“Create a single regex that matches all characters that are not a number or a vowel.

had no problem understanding the vowel part but not a number, like there are infinite numbers got me confused lol

Yes, but you are matching individual characters here, and so there are only 10 numbers that a character could be.


if I am matching it off the string, it’s still 11 characters, where did you get 10 numbers from?

Would you prefer digit or numeral?

The use of the word ‘number’ is consistent with previous lessons;1:

Yes, you are applying the regex to a string but the pattern is only looking at one character in the string at a time.


This says “For each character in the string check if it is not a vowel and not a number”. Since the pattern is only being applied to one character at a time, how many possible numbers, digits, numerals, etc… are there for a character in the string?
