6 Things to Mind if You’re Planning to Study React.js

React.js is a library that allows for creating complex interactive interfaces with the help of components. Its perks include the independence of the created components and the selective rendering of elements based on the changes. So, if you listen to your teacher or mentor from courses attentively and follow their recommendations, you will be able to use these advantages.

So, you decided to have extra courses to add one more technology to your stack. Or, are you going to master it yourself? That’s also an option, but it will take more time. Studying something without professional guidance leaves room for more mistakes; hence, more time will be needed.

In case you have other subjects to learn, using “write my essay for money” would be the most time-efficient option. Otherwise, everything you need to know before you start is listed below.

React.js Does a Lot of Routine For You

Let’s start with the good things. The first one is that React reduces the amount of code for operations like handling event listeners. All you need to do is to indicate a method in the inbuilt markup similarly to attributes in HTML. No need to access elements via variables or explicitly add and remove event listeners.

The mentioned markup is one of the main perks the JSX syntax offers. It resembles a Handlebars template inserted in JavaScript code. So, there is no need to switch between HTML and JS files. Just work with JavaScript in its modern appearance that also allows you to tweak the process of the website building by giving access to the methods under the hood.

Components Are Life Savers

A React component is an encapsulated element that can be represented as a function or ES6 class. It always presupposes rendering a particular part of the markup. The code of two components should never overlap in one file:

  • write the code for them in separate files;
  • import them to the file with their parent component(s);
  • insert references to them.

This way, the code looks less messy.

Structuring Is a Must

One of the main roles of React components is to split complex logic into… components. The higher one stands in the hierarchy, the fewer lines it should have in the render method. When the latter contains mainly names of components, it increases the code readability significantly, and that’s quite important not only later, in real projects, but also during the studies.

Imagine yourself writing everything in one file for several hours or even trying to submit that file as completed homework. The teacher will send your work back for revision since such a format basically breaks the main rules of React. As soon as you try to split the logic, your code will look like a crash scene.

Probably, there will be no time left to attend to other subjects, and you will hectically google “do my homework with native authors” to submit at least the essay you didn’t manage to start. Eventually, you will have to rewrite the code almost from scratch. So, make sure you organize the files and code properly from the very beginning.

Another point about structuring is that the source folder should contain the one called “components,” and the latter should contain as many subfolders as there are components.

The thing is, CSS/SASS files are also created for each component. So, to avoid piling up numerous files and simplify the navigation through the project, the rule of separate folders was created. At first, it sounds like it only complicates the process of coding, yet, later, you will realize that it’s just a matter of a habit.

Code Editors Support JSX Poorly

At least if you compare it to the speed at which you can unwrap the minimal markup in HTML. The pace at which you will write the code, especially at the beginning, will be lower than usual. However, it’s mostly curable. Extensions like ES7 React / Redux / GraphQL / React-Native Snippets and ReactJS Useful Snippets can help you work faster and overcome numerous corrections and revisions.

Websites Built on React.js & SEO

Google crawlers don’t handle JS as well as HTML. A webpage written using React contains only static markup represented by a couple of <div> tags or so. So, there’s nothing to scan to optimize your website for search engines. It’s a curable con though, that’s why you will need to use Next.js.

3 Important Topics to Revise Prior to Learning React.js

  1. Classes – the lion’s share of the code you will write in React will be represented by ES6 classes extending the React component. It also has a constructor and methods. So, keeping in mind how classes function in general is a must. The better you understand this topic, the less confused you will be.
  2. Webpack Bundler – React.js runs on Webpack, so knowing its basics is a must. If you have never worked with bundlers before, it’s especially important to grasp the idea of how to operate them in general. Try practicing using Parcel first.
  3. Types of Imports – with React, you will have to import even images, leave alone the components to connect them to each other. So, revise the ES6 standards of importing elements and files.

Takeaway

Mastering new technology is always a pain in the neck, and it’s okay. It’s a sign of progress and learning something new. However, you can simplify this process if you revise some basics first and get to know what complications you might face – forewarned is forearmed. So, you’re good to go now, good luck!
