been pretty good with html,css3 and javascript at least i can say for now i am familiar with almost most javascript code i see on the internet so i learnt boostrap as at 2017 and used it twice and neva used it again till now am working on a self project and i started using it again but the true fact about it is that i just open the boostrap documentation and do copy and past then i modify it to my own taste but i feel less of a programmer and javascript especially when using nodejs has alot of library how do u experience programmers keep up with all this liberaries or framework and type the code off head or do u also do my thing of copying and pasting as well? will lyk to know your thought about this ure response is highly appreciated thanks.
