Im a senior/ lead dev and I do alot of getting jr devs up to speed. One of the new hires was asking about FCC and it seemed ok at first until he got to the ES6 module. There is next to no explanation on any of the topics and the code examples are too vague at best. I have been coding with ES6 since 2015 and I found it hard to follow some of the FCC assignments as they had almost nothing to do with the explanations/ examples.
If I can be blunt it is disingenuous to make the commitment to teach someone and then give lessons that lack needed info. Perhaps FCC could re-title the ES6 module to “things to look up on google, learn on your own, then come back and answer our questions”. I know this is free and you get what you pay for, but you also put your name on what you do, please do a better job FCC.
