Okay, Ive heard MongoDB and SQl plays the same role in the backend, and as wwell as the node and PHP, what do you think is the best combo to learn, PS Im actually not saying i wont learn the rest, im just going to set them aside and proceeed to 'em after ive finished the first two
For web development I think you should probably go with the combination of MongoDB and Node.js. These are the popular technologies right now.
If you are familiar with JS you will get the hang of Node.js in no time.
MongoDB is also a very easy to learn Database manager.
There are lots of courses which teaches this combination and I believe its the most preferred one .
