3 Must-know fundamentals of ReactJS

Many developers and experienced individuals make the error of going right into ReactJS (or another library and framework) without knowing the prerequisites. Here are the fundamental ideas that you should be familiar with before diving into React.

If you’re learning React and getting stuck on these kinds of problems, you’re probably making mistakes in your learning. Without a doubt, ReactJS is the most popular library among frontend developers, and its popularity is growing by the day.

The website built with ReactJS looks great, and most beginners in development are drawn to it (created by Facebook). However, many developers and experienced individuals make the error of going right into ReactJS (or another library and framework) without knowing the prerequisites.

In this tutorial, we’ll go over certain requirements and fundamental ideas that you should be familiar with before diving into React:

1. Javascript and ES6 Fundamentals
You can’t improve your React skills if your javascript fundamentals are unclear. It is one of the most important skills to learn before moving on to react during interviews. Javascript is one of the most perplexing languages for programmers because it ignores little faults that can cause problems in your project if you don’t spot them right away. So make sure you understand the fundamentals of javascript before moving on to the sophisticated versions of ECMAScript5 and ECMAScript6.

2. CSS and HTML
HTML and CSS are the foundations for all front-end developers. So, before you start learning to react, make sure you know how to write HTML and CSS. You should be able to write semantic HTML elements, CSS selectors, classes, a CSS reset, box model, border-box, flexbox, responsive web apps with media queries, and a frontend application utilising HTML and CSS.

3. Package Manager (Node + Npm)
When using ReactJS, you’ll need to install a number of minor software packages. Modules are javascript libraries that can be included in the Node project, and packages in javascript contain all the files needed for them. Packages include two items… js files Plus package.json files To install these packages, you will need a reliable installer that will allow you to effortlessly download and install software packages without having to worry about dependencies.
