Use React to Write Better TypeScript

How to write better TypeScript

TypeScript: love it or hate it, you can’t deny the fact that it’s spreading like wildfire. In fact, according to the Stack Overflow 2019 developer survey, it was listed as the third most-loved programming language and the fourth most-wanted.

Now whether the survey accurately represents real-world sentiments is up for debate, but the fact remains that TypeScript is here, and it has come to stay. It’s so pervasive now that it has replaced vanilla JavaScript as the language of choice for many packages in the JS ecosystem, with some like Yarn even going as far as rewriting their entire codebase in TypeScript.

I feel one of the reasons for this meteoric rise to success has to be the fact that TypeScript, in essence, is just JavaScript. This makes the entry bar a lot lower for existing JavaScript developers, and the fact that it’s typed may also attract other devs who prefer the features typed languages provide.

This cuts both ways, too, because the ease of picking up TypeScript has led to some cases where the language is not being utilized as effectively as it could be. Many developers still write TypeScript like they’re writing JavaScript, and this brings with it some disadvantages.

We’ll be looking at some real-world code written in TypeScript that could be improved to make better use of the language’s strengths. This is by no means an exhaustive list, and I welcome you to list some you might have noticed in the comments section below.

Some of these examples involve React because I’ve noticed some instances where React code could be improved by simply making use of some TypeScript features, but the principles are by no means limited to React. Let’s dive in.

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.
