Where to learn node.js

[Privete_member__1355875]

Hi,

I have done an OpenSAP course about Building Apps with SAP Cloud APM.

Well the point is, I am still new in node.js and when I try to find information about what is the meaning of the code they are using in the course, I did not find anythig I am really happy with, because the CAP Cloud guide does not cover 100% all the stuff is used there.

For example:

the meaning of "each" in

srv.after( 'READ', 'Books', (each)=>{ if (each.stock >)}

or

the meaning of the "map"-function in order.Items.map()

or

which are the different ".where, .set, .and" variants in cds.ql, and a properly explanation of the Fluent Expressions…

Is there any way to learn those things from an unique source? Any info about how and why they write the code so and an explanation of the functions used.

Thanks!

Codecademy is a resource - see https://www.codecademy.com/learn/learn-node-js

I have used them before, not for Node.js but for JavaScript in general - the course was good
