Welcome back to D Guides folks.This post is valuable for newbies for react development.I am sharing about few tools you can use when developing react applications.It is important leaning tools like these same as understanding a framework like React.These tools will help us to maintain high code quality. 1. Prettier Prettier is a tool which will format the code consistently according to the standards.First step to do is install prettier as a developer dependency.Why developer dependency is the next question hops into your mind.We don't need to have prettier as a dependency when we are deploying the application so that is why it is installed as a developer dependency.Then we need to install prettier plugin for vs code.VS Code is my first choice when doing web development.Then we are changing two things in preferences.First thing is enabling format on save.Other option we are enabling is require config.By that we ensure that prettier will run only on the projects prettier h...

Even though you are a beginner for node js you all know that Node.js is single threaded.But we use Node.js for powerful backends and we can include concurrence functionality into a Node.js application using events and call backs.In simple terms 'Event Loop' is what permits Node.js to perform non blocking I/O operations.Node.js uses event in large scale and it is the reason behind the speed when comparing to other technologies in the same stack What exactly is 'Event Loop' ? Everything happens in Node.js platform is because of events.'Event Loop' mechanism is inside the library called 'Libuv'.Since there is only one thread both userland code (code of the user) and event loop run in that same thread.Every callback is handled by the so called mechanism 'Event Loop'.Every userland code running in a Node application is a callback.Event Loop is behind the huge success of Node.js development.As I mentioned earlier every Node application i...
