Introduction:

JavaScript is a dynamic typing language, which means types are determined at runtime:

let Sentence = "I am programmer" //Here Sentence is  string
Sentence = 20 //Here it morphs to Integer

String Sentence = "I am programmer" 
Sentence = 20 //Here it will throw an error

React is written in JavaScript, we do not have a direct way to check about passed props type before computation and rendering, it is painful…


When to use SPA, SSR and SSG
When to use SPA, SSR and SSG

Introduction:

Over the past years, We had base pure Front-End frameworks like React, Angular, and Vue, all of them provide client-side rendering(Single Page Application), then we discovered our needs for different renders modes. We had different renders modes and different frameworks support each one of them, but the problem many developers can’t quite wrap their head around when to build an app as a pure SPA and when it’s better to use an SSR or SSG.

It’s clear that there is no sense to use an SSR framework for building a todo app, as it makes no sense to build your…

Important Notes before beginning our Journey:

There are no Breaking Changes, Completely opt-in. You can try Hooks in a few components without rewriting any existing code. There are no plans to remove classes from React. 100% backward-compatible. Hooks don’t contain any breaking changes. …
