Learn React and JavaScript Programming Basics with Example Code

React is an open-source JavaScript library that helps you build user interfaces. It’s a component-based, declarative, “learn once and write anywhere” tool.

With 164K+ GitHub stars, 30K+ forks, and close to ~10 million weekly downloads, React is undoubtedly a great user interface library to learn and use.

If you are a developer getting started with React or thinking of using it in your side-projects or enterprises, this article is for you. If you started learning React a while ago but you’re finding it hard to grasp the basics, give this article a read.

TL;DR

This article is lengthy but should be a fun read if you want to learn React or if you’re working with it already. It answers these questions:

  • How does modern JavaScript knowledge make you an efficient React developer?
  • What kind of changes do you need in your mindset when you design and develop a React application?
  • What are the ecosystems you need to be aware of and why?

Just chill, grab your favorite beverage, and enjoy the article.

Why I Wrote this Article

At the beginning, when I was learning React, I made the mistake of not focusing on a few essential fundamentals. As my knowledge grew more substantial, I started learning those concepts and found myself more comfortable with React.

Many of my mentees discussed the challenges they faced when dealing with React which also centered around these fundamentals. So this motivated me to write this article and share what I’ve learned.

Modern JavaScript Concepts You’ll Need to Know for React

Flexibility with Modern JavaScript

The standardized name of JavaScript is ECMAScript. ECMAScript 2015 (which is also the 6th edition, and why it’s called ES6) brought lots of cool features and new syntax to the JavaScript language.

React, and many other modern user interface frameworks and libraries, work well with ES6. It is essential to know its modern syntax and new features to make coding much easier.

This doesn’t mean you can not write a React application with ES5. You can if you have to, but you’ll kind of be doing things the hard way.

Here are a few concepts you need to learn well.

  • How to Use Let and Const in JavaScript
  • How to Use Template Literals in JavaScript
  • How to Import and Export Modules in JavaScript
  • How to Use Arrow Functions in JavaScript
  • How Destructuring Works in JavaScript
  • How the Spread Operator and Rest Parameter Work in JavaScript
  • How to Use Classes in JavaScript

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

The Most Important Programming Lesson I Ever Learned

In the fall of 2012, I walked into my graduate advisor’s office and asked her which computer science class she recommended for me to enroll in. I explained that I was a complete novice in programming. She suggested Introduction to C Programming.

After attending a few lectures, I discover that the majority of the students I spoke to in this introductorycourse had some prior experience in programming.

Six weeks and 80 hours of work later, I dropped the course.

Enter spring semester of 2013. I enrolled in an easier computer science course, Introduction to Computer Programming via the Web. I breezed through the first quarter of the course, executing HTML and CSS with ease. Then, we started Javascript (JS). That feeling of constant anxiety and stress from my previous computer science course returned in full fashion. It was too late in the semester to drop the course, so I asked a friend for help.

Although we still talk about programming as a standalone career, the dominance of technology in our lives makes it clear that coding is much more than a career path. In my opinion, computer science is more than a college major or a high-paid job; it’s a skill, essential for thriving in a modern-day economy.

Whether you work in healthcare, marketing, business, or other fields, you will see more coding and have to deal with a growing number of technologies throughout your entire life.

Now that we live in a tech-driven world, asking “Should I learn to program” is almost synonymous with “Should I learn to speak, read, or count?”

The short answer is: yes.

How to start your journey in coding? The good news is there are plenty of resources to support you all the way through. To save you the trouble of looking them up and choosing the right ones, I created my list of learning platforms that offer well-rounded programming education and help you stay competitive on the job market.

Learning to Code: How to Boost Up the Process?

Let’s face it: people are impatient by nature and most likely want things to happen faster in their lives. I would apply the same to code learners. Students, when starting to learn programming, first wonder how to speed up the training and make a career as a programmer as soon as possible.

I am not the one who convinces everyone that learning to program is a lightning-fast journey — the other thing is that it is not as difficult as people think. All boils down to interest, passion, regular practice, and patience, of course. I also often recommend different online and offline resources to my students to make their learning process easier, more effective, and faster. And in this post, I will share a few tips with you.
