Specify Exact Number of Matches, Free Online Coding Tutorial

In this lesson from freeCodeCamp's Regular Expression course, we take a look at a regex that specifies an exact number of matches. Using this regular expression we can look through the text and if we were, for example, looking for "hah", with the the "a" letter 4 times (haaaah), we can use the regular expression, /ha{4}h/ which allows us to specify the number of patterns it should match (in this case "a").
