React or php or SQL?

Question

I just started learning coding a month ago, I want to create an simple wiki app, I have complete html, csc, currently on JS. Should I go to react straight or PHP or SQL first? It seems that database/backend is quite an important part to understand where and how the data flows.

Answer 1

this comparison is not fair!!
React is a web front end framework
Php is back end scripting language
Sql is database query language.

Answer 2

i mean should i dive straight into creation or should i continue learning more stuff?
