Please tell me some challenges to do while learning web development.

Answer 1

You can make your own website, say e-commerce, you can look at simulating any one module say, shopping cart. You should offer the user to add items to the cart, edit number of items, delete items, clear cart, etc. These are just few, you can add many more operations that you can think of. Start with something small and gradually increase the number of modules.
