I totally get we trying to learn and part of that process is looking at a Utility Library like Lodash, and trying to reverse engineer solutions based on what we’ve learnt so far.
This project was hard, but very rewarding until…the Inverse() which had me for 2 hours only to realize that the video led by the instructor was just wrong. This is a horrible experience.
I just moved on after this. It’s also no help when the instructor is just reading what she is doing. We can all see what she is doing but the why, the how, the different possibilities is lacking so hard from this.
The YouTube video is full of angry, depressed students who feel the same.
Please re-do the entire project and video.
