I keep worrying about my future when i study more and more. I'm not 100% sure that I'm taking the right path to be a software engineer. I found so many great developers on YouTube community and they provide so many useful information. I do live coding streaming everyday when i study and also try to do at least 3 sessions. 1 session is consisted of these(Algorithm/ Vanilla JS/ React). When i have tech interview, they expect me a decent level of algorithm and JS toy project implementation. So i found out that learning React isn't important at this point. Although it isn't important until i build up the foundation, i'd like to be a React developer and would like design whatever i want to.   Coding test - codewar 1   CSS - grid/   JS - Sec 9   React -   A bit of Yelp Portfolio -  List the 100JS projects Job hunting - Karrot for  internship  Apply SW maestro
