Just came back from Assertions chapter of JS RegExp Documentation. Thanks for teaching us the use of \b. TBH, at first glance, I thought you had a typo in your arrow function. Then after trying myself and reviewing how reduce method actually works. Now I understand why you could save that + in front of a. It's just beautiful!
