    Had a terrible time understanding the methods for arrays and this has been the most helpful yet! Not only did you go over each method but exactly what they did with very clear examples. Thanks so much for making the video!

    Thanks, really great walkthrough. I've always been a bit unsure about reduce() but if I understood correctly its when you want to loop through the array and have each of the values contribute to something bigger to represent the array, the video helped a lot. I never realised the some() and every() function existed, I'll definitely make use of it to ditch Boolean flags and For Loops!

    Thanks Ganesh, glad you found it useful! Yeah, I think you're right about reduce - it's when you want to loop through and reduce the array down to one value that represents something from the array (like the max value or total)

    @DoableDanny at 7:43 I don't understand why you had to use the spread operator instead of just copying names into namesCopy? Is it because, technically, namesCopy would reference the same array in memory if you didn't do it the way that you did? Great video, by the way!
