Implement Filter Using Reduce
In this short video, we use the reduce method on the array to define a filter function to help build intuition for how reduce works. I find that reinventing the wheel, especially when introducing constraints, is a great way to develop new techniques and gain a deeper understanding of your tools.
Edit: I realize I made a mistake around the 3:34 mark of the video and the variable name inside of predFn should be currentVal instead of currentValue! My apologies, I'm still getting used to making and editing videos and I'll work to do better in the future!
