1Flask is a Python framework for web development.

3When creating simple static sites, there is no need to use backend frameworks.
4However, when creating complex and large sites that are backend heavy,
5you will want to use a backend framework. Currently, the 2 Python frameworks
6that are the most useful to learn are Flask and Django.

8Flask:
9Micro and light-weight framework that is easy to learn.
10
11Django:
12Complex, full-stack framework that is extremely powerful.
13
14For smaller projects, Flask will work. However, for large ones, you might
15consider learning Django. I suggest you learn Flask first and then Django.
16
17Additionally, considering learning Node JS because even though it is in
18Javascript, it is extremely popular.
