Match Characters that Occur Zero or More Times Need Help

Tell us what’s happening:
why oPhrase.match(goRegex) return null even though I still see the “o” character in the oPhrase string?

Your code so far

let soccerWord = "gooooooooal!";
let gPhrase = "gut feeling";
let oPhrase = "over the moon";
let goRegex = /go*/;
soccerWord.match(goRegex); // Returns ["goooooooo"]
gPhrase.match(goRegex); // Returns ["g"]
oPhrase.match(goRegex); // Returns null

Your goRegex matches a “g” followed by zero or more "o"s. Since there is no “g” in “over the moon”, it won’t match.
