Understanding Regular Expressions on freeCodeCamp 2021, Match all Numbers Regex Pattern Matching VIDEO
In this Regex lesson from freeCodeCamp's Regular Expressions course, we take a look at a shorthand character class for [0-9]. If we want to quickly create a character class that will match a digit, we can also do the character class \d. This will return the first character that is a digit. In this specific lesson, they want us to find out how many digits appear in a string. Since \d only finds the first character, we can apply a global flag to help us retrieve all the digits that appear.https://believerationally.com/shop https://ValeryeDoesResin.com https://Ananomyx.com
