How do I become better at JavaScript?

Hi Pooja,
A standard method of becoming better and better in anything is to practice continuously. In the field of logic and creativity, there's no end, and you can keep going and set new records with your findings and next goal for yourself.
Now, in case of programming, to become more comfortable with any language is to go beyond writing small programs and think bigger. Now what's more prominent, well let's say an application which in some way useful to the users/customers. Few ideas could be:
- Songs website
- Real estate website
- Social media website
- Kids toys website and anything you can think of.
Now if you think that these kinds of websites already exist, the answer is Yes. But there's always something left in any solution, and that's where innovation starts. You can analyse other sites of your choice, find what you would have done if given a chance to improve that site and work on your idea.
To tighten your grid, do the following:
- Use JS frameworks such as Angular, Node.js etc. to diversify your JS knowledge.
- Use free (or paid) APIs to broaden your reach with more content.
- Understand how to clean up your code to make it more useful and fast.
- Understand and work on local storage to set and get the user's saved data.
There're many more points which you can go for and the above mentioned are to start with. The more you dig, the more chances of finding gems you get.
This answer can be as long as it gets, but I'd instead stop here. Assuming that you got the idea, I wish you all the best in your new journey to take your skills to the next level.
