Here’s a few suggestions:
- Learn a framework like Vue or React. Start with Vue, it is very simple and very powerful. It simplifies development process and makes it more fun. …
- Build an Electron app. It comes with Node. js and it will let you practice working with more advanced concepts.
Getting yourself acquainted with syntactical stuff should not take you more than a week working 2 to 4 hours daily. Then you would have to go through the advanced concepts like the Closures, Web APIs, Event Loop, Prototype chain etc. This is gonna take some time. From one month to a couple of months.
