​​What makes NodeJS distinguished from any other programming platforms is how it handles I/O. We hear this all the time when NodeJS is introduced by someone saying “A non-blocking, event-driven platform based on google’s v8 javascript engine”. What do all these mean? What do ‘non-blocking’ and ‘event-driven’ mean? Answer for all these lies at the heart of NodeJS, the Event Loop.

​​So, you’re looking for a way to spend your Saturday, and you come across the brilliant idea to go spend the entire day at an organized hackathon. Fun! But not necessarily.

​​Common scenario: your team maintains dozens of Jenkinsfile/.gitlab-ci.yml/whatever, each one specific to its projects needs. You have tried to reuse these continuous integration scripts from one repo to another. But that is hard because each project has its own tech stack, versions, dependencies to other tools, etc.

It felt like it takes too long to test the whole suite (32 tests only) as well as test a separate file in isolation with watch mode. The direct consequences of that are that developers are not enjoying the process and trying to avoid touching unit tests. Product quality suffers in the long run.

​​If you are reading this you probably know how javascript manages the scope, but let’s refresh our memory. Javascript manages scope through its functions, meaning that any variable declared inside of a function is scoped to that particular function, and cannot be accessed from outside of that function. Now globals, are variables that are declared outside of any function, or variables that are used without being declared.
