it’s never good to rely only on one language. a programmer should go for the language, that best suits/solves the problem.

Use JavaScript for interactivity. Use php for data persistence. There are many other differences but those are the biggest reasons why someone would want to use them. All depends on what you want to do. You should learn both.
