3 Steps on how to upskill & learn any New Tech as Frontend Engineer πŸ”₯

1. Stop learning just the Code of the Tech. As you know with every version update Code changes. See React, lots of APIs have changed.

2. Every Framework, Library or Tech comes with a purpose to solve a problem. Learn what’s the problem. People don’t release just for show off of New Tech.

3. Don’t just jump to YouTube Tutorial, β€œ15 mins of this Tech, that Tech”. Rather, refer Conferences, Talks, Tech Blogs, Podcasts by the Official People whoβ€˜ve built it (No one knows better than them ⚑️)

4. Command Line (This can be done parallel to the above 4)
Believe me when it comes to Java development Command line skills will be a boon for you guys.
Start with the basics for eg : install and setup java with Command Line only.

Start using Linux distributions ( it's very necessary ) go to a virtual box or dual boot your systems with any of Ubuntu , Kali Linux , Manjaro etc

5. Learn Servlets and JSP and then go for a framework ( Spring boot
