How long did it take you to get a firm grasp of the Javascript fundamentals?

Question

I'm currently almost 3 months into learning Javascript and I'm still trying to get a firm grasp of the fundamentals of JS so I can build stuff.

Answer 1

if by fundamentals you mean data types, control structures and operators, then three months is enough to gain a decent grasp of them with an adequate amount of practice. in fact i learnt the fundamentals of programming with batch programming before delving into javascript and was able to make a math application with this limited language.

Answer 2

I remember you :P
You just need to write code with whatever you got. As soon as you know how to print stuff to the screen, you can write programs that tell you how many golf balls fit into a swimming pool, or spell a name backwards, or print a 20x20 national flag onto the screen, etc.
If you know about loops, you can write tic-tac-toe or checkers or chess or calculate the amount of days in X years or pull random Britney Spears quotes from the internet every five seconds.

I've been at it for over 10 years and let me tell you, you are never done learning.
Ideally you want to discover new language concepts by writing code and thinking "hmm, I wonder how I can do X" and not because a tutorial tells you to learn X.
That's not to say tutorials are bad, but they are a supplement, and not a substitute for writing programs!
