Learning the programming language

Question

I want to know that how do you know that you learned a particular language.

Answer 1

That depends on the context. Who's asking, and for what reason?

I suppose (just as an example for an employer) a vague statement like 'I know JS' might be less interesting than 'I made that and that and that program'. It should give a better impression of how much you can do.

Answer 2

You'll never have fully learned a programming language.

There's just too much in all of them, and they evolve.

You should concentrate on writing code. With every successfully finished project, you'll know a little more.

Answer 3

HonFu
Ok
But if someone ask you that "did you know this particular language", when to say ya I know it.
