Code improvements Suggestions [WIP]

[Neha]

Describe the bug
This would be a list of code improvements to do in the code:

1. Create a reusable component of "form". "Enter your email" section is required more than 2 places.
2. Homepage -> Previous talk section can be break into small component. map logic should be outside JSX as a separate function
3. Homepage -> Form on homepage should be a separate component
4. Homepage -> Some content is hard coded and some is coming from config. Need to sort this out
5. Header component -> Requires code optimizations. The HTML can be optimize by removing extra DIV and Make 3 different components: LOGO, Nav, and Register Button.
6. Footer: map should be outside JSX

A few issues can be taken care with this issue:
