I am almost done with frontend development and know JavaScript. I wanted to know if it is necessary to learn any frontend framework, and what would be the advantage of using them? I also want to know which of the frameworks to choose, especially on factors such as responsiveness(like mobile version or web app)? I am also open to suggestions of using frameworks other than the above two such as Vue.js etc. Thanks in advance.

I have just started learning some basic machine learning concepts. So which of the following frameworks is better to use: Keras / TensorFlow/PyTorch. I have prior knowledge in python(and even pandas), java, js and C. It would be nice if something could point out the advantages of one over the other especially in terms of resources, documentation and flexibility. Also, could someone tell me where to find the right resources or tutorials for the above frameworks? Thanks in advance, hope you are doing well!!

I have just started LEARNING BACKEND so which framework do you think is best to learn first(among flask, node.js and PHP) and use, and which backend programming language should I earn or is important? I have some prior knowledge in python and javascript.it would be nice if someone could point out the advantages of using one framework over the other.
