Hey there guys,

I am interested in learning Node.js and came across a tutorial that shows how to build a local library website using Express.js and Node.js.

The site mentioned that the only pre-requisite for the course is basic knowledge of JavaScript. I did have basic knowledge of JavaScript enough for stuff like DOM Manipulation, form validation etc.

But as I advance through the course, I feel more as if I dont have the necessary basic knowledge to go through the course comfortably.




For example, I am struggling to understand the above code Snippet. I really do not know about the usage of angular brackets in JS and had never come across it until now.

This definitely points out the fact that I am missing a substantial basic javascript knowledge.

Can somebody please guide on what all is mandatory before learning Node.JS? please don't say web system architecture and internet security to complicate the question. My question is specific to Javascript and I'm talking about hobby scale projects here.

I meant square brackets in the above question and not angular brackets.

Well, how did you attain your current knowledge? Did you ever read through an entire basic JavaScript tutorial anywhere?

I did. But I think all the tutorials I have gone through was focusing on how to use JS just as a front-end toy for validation and message displays etc. Things like callback functions and asynchronous programming techniques were never discussed.

In short, they were too basic I guess.

So I would like to get some guidance on the roadmap to follow to understand JS basics before learning node. Kindly if someone could guide, it would be very helpful.

If you already know basics and syntax, my book Secrets of the JavaScript Ninja goes into great detail regarding functions, closures, callback and other JavaScript concepts.

Thank you! The answer I have been looking for. Most books I had a look at so far seemed to stop at DOM manipulation. But this seems to go into detail.
