Specify Exact Number of Matches(why exactly is this code not working)

I know the answer /Tim{4}ber/

but could someone explain why something like /.m{4}ber/ is not working , why exactly does it not return 30 m’s part. They all work except with the 30m’s in it.

Your code so far

let timStr = "Timmmmber";
let timRegex = /.m{4}ber/; // Change this line
let result = timRegex.test(timStr);

Link to the challenge:

Because the . will match anything, including another m. So it matches Timmmmmmmmber (matched 5 letters “m” and “ber”).
