It's a massive overview and there's tons of things listed and they all link to some great videos...
Also, the "deeper frontend" has CSS Tools? No, deeper frontender learns those last to "level up". Newbies use CSS precompilers and frameworks like bootstrap. Experienced devs steer away from those things because they make life easy the first time around, but in a year when you have to go back and debug something in that old code from a new computer, or god forbig you have to move the site to a new server, you will not want to have to install all that crap. Coding cleanly ends up being much more maintanable. Especially the reliance on Task runners ends up being a pain in the ass later on.
JS frameworks, to me, i just don't get the reasoning behind doing heavy lifting in JS rather than doing it serverside. Single Page applications work just as well with ajax calls, but i'll accept that I don't know much about single page projects cuz most of the things I work on are more complicated than that and I like to think that as you work more in the field you'll end up doing much more complex sites that do not make sense as one-page apps.
For backend they also suggest to dive right into frameworks. Why can't people just write code to do things? Instead they rely on a framework and the first time they run into something complex they just can't cut it.
He recommends node.js....used by 0.2% of sites opposed to PHP, used by 95% of sites....that fucking blows my mind.
Also not sure why Apache and Nginx are behind "caching"...there is a tiny bit more to them than that, you know, like your entire domain setup, server security settings, and access levels, and that little file on linux sites called an .htaccess .....he just kinda didn't remember those i guess.
I do like their "No matter which route you take" list as those are absolutely things any developer should know. I'm not sure why they mention "hostgator" as a good idea for web host setup when it's not nearly as well known or popular as godaddy/bluehost/networksolutions/1and1 etc. Also, FTP is more about the application like WinSCP or Filezilla, but sure.
Last note: I hate how he keeps saying "looking to level up"....seriously...you have to "level up" every single one of these skills over the years. You don't go from one to the next and forget about the previous. It never ends, you go deeper into the rabbit hole and it gets cooler and cooler and you eventually learn how to improve every step before that, well, you will if you're paying attention and willing to keep learning.
