What is the use of learning all the codes for web and android apps?

Question

Hi guys. My question is, when we have Ready-Made codes in the Google and other sites for web and android development. What is the use of learning all the languages from the beginning to do web and android development?

We can even develop a website and android app by using the ready made codes available in internet!

Answer 1

then dont learn, simple
if u think copying and pasting straight from the internet is what u gon eventually do, stop learning

Answer 2

learning a code gives you the chance to go in depth of the code and language. you will come to know about the basics of the code and the use of the code for different places.
