5 Things to Know Before Learning React

When You Haven't assembled a single-page application before, React Forces one to level-up your expertise. React since a library has got a lot to offer - you can build shareable components that have a very clear stream of data (making debugging much, much easier). Many instances, ReactJS development service just enables you to write JavaScript to get your work done.

For the last year or so, I have been composing apps with React and Redux, After seeing folks have trouble with obsolete tutorials and blog articles, and also the Java Script ecosystem generally speaking, I compiled a set of things you may want to know before you begin learning React. The list below will seem exhaustive, but once you feel eloquent in these concepts and techniques, it will make building your first app in React easier and more fun.

1. Read other people’s code

React is shifting so fast that there are a lot of out-of-date Weblog Tutorials and posts. It's frustrating to follow a few instructions as a newcomer to React, then encounter one or, even worse, and have your code softly neglect without any explanation.

 

2. Know your development environment

It's impossible to be a front-end developer (or even front-end engineer) without knowing your development environment.

 

Frontend development has a huge focus on taking every day Java Script And utilizing it to complete various things -- as an example, making newer Java Script work in old browsers via polyfills, altering fashions with Java Script plugins, animating and styling SVGs - generally speaking using Java Script to get around browser constraints.

3. Know a bit about npm

NPM is your Node Package Manager. You can use either npm or another instrument known as yarn to install packs to a node modules folder. (There is a little bit of controversy over which tool to utilize; they both work.) Thus, instead of visiting a website and then downloading a JS file, you just use the command line to catch those JS files out of a central place named the npm registry.

 

4. Know CSS and just how to make things look great

Knowing CSS goes a ways with React. Based on my experience, there is a ridiculous shortage of React developers that can trace and Make things seem pretty -- or desire to. React is JavaScript, however, with responsive design, being proficient at CSS is now a speciality on the planet.

 

That said, there’s only so much React you can write with existing component libraries, and in some time your designer or product owner is going to want to possess something that looks more bespoke.

 

5. Be ready for shift

React.createClass is no more available in the latest version of React (you have to import it like a separate module), also PropTypes is a module you also now need to import. These breaking changes are things that you wouldn't know about if you did not see the React site, also when you're following tutorials, they are out of date and not work with you personally.
