In computation systems, names like concurrent, sequential, parallel, serial, synchronous, asynchronous, non-blocking, shared state, message passing, and likes, stand as a forbearer for the actual task that happens in a system. While all of the above techniques have their use cases, in the world of JavaScript, asynchronous and synchronous programming never leave the tongues of its programmers. In his Concurrency glossary, slikts (dabas@untu.ms) wrote about asynchronous, he said: Asynchrony means “not happening at the same time”, and asynchronous message passing is a communication model that does not require the sending and receiving to be synchronized, meaning that the sender isn’t blocked until the receiver is ready. ...

AdonisJS was built for the NodeJS Artisans taking after the concepts of Laravel - The PHP framework for Artisans. AdonisJS did a great job porting these concepts into JavaScript, it maintains the namespace even though JavaScript does not support that, it using its own fast, easy and extendable view engine and many more, but some features of Laravel are not shipped with AdonisJS by default.

I’ve been through a variety of programming languages, which always turned to be that the deeper I dive into a language, the more “aha” moment I get. I always feel like I have gotten what I wanted and have to look no further to attract the priceless attention of my fellows. ...
