At the moment your thread has 40 views with one response. The 30+ other people are either developers who know this is a recipe for failure and don't even know how to break the news to you and they just walk away or people who, like you, want to learn so much and have gone off to go and create their own 100 day challenge.

I won't even try to put myself in any of those categories but I'll just drop my opinion on the floor, its your choice to pick it up or kick it aside.

Except you're working in a team or you already have a backend developer, you cannot focus on learning frontend development without dabbling into some backend stuff. You front-facing apps will need APIs to test their functionality on. So you should be targeting the role of a fullstack developer, not frontend alone. Since you have a desire to learn Javascript, it makes it easy to target fullstack because you can use JS for frontend and backend.

Themeforest has great themes, very great themes and I can't tell you how many stunning websites I made for clients with just reusing themes several years back. Looking back, I won't touch themeforest themes for anything, at least not at the beginning. Themeforest themes and all themes in general form an abstraction layer between you and the inner workings of HTML, CSS and Javascript. I would learn those techs first and master them before dabbling into any themes, if ever.

Those FreeCodeCamp(FCC) certificates are useless. I don't know where to explain from... take it or leave it, I have all 6 FCC certs and they are useless. I dont regret the time spent in getting them because I just casually took each cert quiz.

Your plan to build a clone of Slack, Udemy in 100 days is unrealistic considering each of those services took several months to build by a team of people who were not actively learning the tools they were working with.

So you have 100 days. Here's the only Udemy course you need to focus on to start your journey into fullstack development.

As for certifications, keep that one by the side. Any serious employer will be interested in your Github and Stackoverflow account over any certifications you show. Certifications in web development is useless to a large extent. You can think about certifications later on when you want to specialise in related fields like project management, security, devops and testing.

P.S: Please dont spend 100 days writing code. You will burn out and your codes will look like hell (even if they work). Pace yourself nicely. A little learning, a little fun outdoors or gaming or anything to help your brain relax.

Here's an earlier post of mine that has more information that may be of help to you.

Here is a piece of advice man,

I don't wish you ill but at least try to learn on the low and make your learning plan effective and not because you see other people doing it.
