Answer 2

First off you will never "Master" a language because they are always updated. possibly the foundations of the language. You will constantly learn new things and ways the use this language.

Continue to write programs get an error Google it and see how others solved the problem. these days you have so many resources so there is no need to master a language .

Goodluck.
