React, which was originally written by Facebook, is one of the hottest web development technologies right now, and it’s only growing in popularity as more people discover how much it has to offer. However, if you’re just getting started with React, you may be wondering how it compares to other hot web development languages like Python or Ruby. To help you decide whether React will be the best technology for your next project, here are some of the key ways that React can make your projects easier and more efficient than alternative technologies.

React JS Basics

A single-page web application is typically designed in two parts. The first part (consisting of HTML, CSS, and JavaScript) stores all data for a given page’s initial load. The second part (usually just JavaScript) handles what happens when that data changes or another piece of information becomes available to render on the page.

React JS

common pattern is known as Data Binding, and React makes this easy to do! When an event – like when a user clicks a button – occurs, we can simply say hey! let’s tell our UI what happened!. Let’s see how this works in a few quick steps with some sample code…
let ids =

What are Virtual DOM, ES6, and JSX?

Virtual DOM is a JavaScript-based framework used in web app development to simulate changes and make them virtually occur. It helps programmers manage large amounts of code efficiently and keep everything organized. It speeds up loading times, makes the code cleaner, and also lets programmers create smoother animations.

React JS

or ECMAScript 6, has many new features including classes, default function arguments and string interpolation. The last one, JSX stands for JavaScript XML, which does not have to be translated from JavaScript into HTML like a regular template would because it has a syntax that resembles an XML document. If you are looking for a more robust language than HTML5 or pure JavaScript, then React will be your best choice because it uses these three languages to work its magic.

Choose an IDE That Supports JSX

The main disadvantage to using JavaScript for your website development is that it’s not server-side. The benefit of JSX (JavaScript eXtension) comes from it being a readable HTML. It does this by allowing developers to import other libraries in order to make a new module for reuse and this makes updating easier than before.

React JS

are able to use JavaScript, but with JSX you are able to just call that module as part of your code. With react, JSX helps update components in response to state changes on the data.

Import an API with Node.js

We want to update all of our items when any one of them changes. To do this, we will use an event handler, which will tell our Item View to update whenever it receives a particular type of event. For example, when the user adds or removes an item from their shopping cart. We’ll call this function setChangeHandler(), and we’ll assign it to be executed every time that the user’s cart or basket total changes in size. Let’s start by adding a function like so:

Render a List of Todo Items

1. The ecosystem around react is easy to get started with, and not hard to navigate once you’ve been at it for a while.
2. Documentation for beginners and experts alike is thorough and clear, which makes it accessible to everyone 3. Building components in react helps developers avoid logic bugs from shared state 4. Compiling from JSX saves developers time, as they can code their UI directly in code 5. Well-supported community of devs on Stack Overflow ensures that all questions get answers 6. The learning curve is fast enough that some new developers can be up and running in a day 7. A job market of agencies or employers looking for people skilled in react means an easier time getting hired 8. Shorter lead times mean faster deployments 9.

Add an Event Handler to Update All Items

This code below updates all the items in a list. This could be useful if we want to make any other updates to these items and want to be sure that we update all of them. In this example, we are just doing a simple change to each element’s text content. We can also use an event handler to do something more complex like changing the item’s class name or even it’s colour!

Promises Are Better Than Callbacks

Asynchronous programming means that different parts of a program will execute at different times. When dealing with asynchronous processes, it’s important to note that there are two fundamental ways to handle tasks and events asynchronously. The first way is callbacks. This process entails waiting for an event to happen, then giving instructions on what happens after. For example, say we want to send out a text message when an employee arrives at work or leaves work (you would use an app like SendGrid or Twilio). To accomplish this task with callbacks, you would need to register an event handler whenever the person arrives and departs. These handlers would use the phone number of the employee in order to initiate texting services by calling some type of third-party service.

Updating State Outside of Components

State in a component should only be by that component. However, there are some cases where it’s necessary to update state from outside of a component. The simplest example is when using setState with an object as the second argument.

React JS

important to call setState at least once before calling force Update so that React knows that changes need to be saved to the DOM.

Stateless Functional Components Are Useful for Small Functions

Using stateless functional components in your JavaScript code can make it easier to see what’s going on and break apart complex behaviours.
An individual stateless function does not contain a key aspect of React components – its state. A stateless function accepts arguments (inputs) and returns a result (output). This type of component works with any framework, but the simplicity of understanding this component makes it work best with React.
This improves clarity, separates complexity into manageable chunks, and provides functions that you can use over and over again. As an example, say you’re developing an application where all items must be unique. You could create one small function for this requirement, which you then use in several places as needed without having to redefine that same behaviour in multiple places.

Use props for Data Flow in One Direction Only

One of the key reasons why a lot of people love React is because it takes away all of the hassles that come with traditional JavaScript. In terms of JS, there are always two sources of data you need to worry about – your props and your state. In other words, if you have one widget on a page (widget A) that needs to call data from another widget (widget B), then widget A will need to receive some information from widget B (prop) before it can work properly. That might sound easy enough but you can start having problems quickly when there are three or more instances on a page which means we’re looking at a potential six different interactions in order for everything to work properly.

How To Be Comfortable Learning New Things

What if I told you that it’s possible to get comfortable with learning new things? Well, it can be! So let’s break down some tips that will help you get.
#1. Make time for practice. You have to have time for your skills to build up, so find a little time every day (or at least 3-4 times a week) and put it on your calendar or set alarms for notifications. Even just 15 minutes each day can go a long way! #2. Look for something that gets you.
