babili VS react-native

The key is that the scoping happens for each iteration, not around the entire loop. That detail is nonobvious, given how many other languages have gotten it wrong, but I wouldn’t say it’s wild.

(If you’re curious how Babel deals with the more complicated cases of continue, break, labelled break, and return, try it out at https://babeljs.io/repl.)

I used https://babeljs.io/repl to know the size after the code has been transpiled.

You must have a basic understanding of JavaScript and be familiar with some of the features of ES6, the most recent version of JavaScript, to follow this tutorial. More information is available here if you’re unfamiliar with ES6. If you are more familiar with the older version of JavaScript, you might find the babel REPL more helpful to see how ES6 code is translated.

The JSX code is far easy to understand, but React, ReactDOM, or browser does not understand it. Babel comes into picture to translate JSX code to equivalent React code.

If we copy and paste the code in a Babel repl editor, we will get the equivalent React elements that we used earlier:

In your node project, add Babel and Webpack. They can “transpile “ your JSX code to browser compatible code. You can try it out here

If your project uses a bundler like webpack or rollup, then you can use the nullish coalescing operator in your code. But if you are using a browser, then you should use a transpiler like babel to transpile your code to ES5. You can use babel repl to transpile your code.

The Babel REPL is an easy way to see what the transpiled output looks like.

There was always a tiny sparkle in me telling me that I want to develop mobile apps but I never pursued it. It always felt a bit complicated for me to learn development processes in a completely different industry. I did try developing mobile apps using React Native but it never felt right for me. Also, I already tried to write some Kotlin code and so far I like it, but the whole Android ecosystem is still pretty new to me and I feel there will be a lot to learn. Nevertheless, I will try to learn it in parallel with Elixir but Elixir will be my primary goal, and Kotlin / Android will go along depending on how much time I will have.

Recently, there has been a notable shift in mobile application development practices. Rather than creating separate applications for each native platform, many developers are opting for hybrid mobile frameworks like React Native.

React Native [ https://reactnative.dev/ ]

Versatility: JavaScript is not limited to web browsers. It's used in a variety of environments, including mobile app development (using frameworks like React Native), game development (using libraries like Phaser), and even serverless computing (using platforms like AWS Lambda).

In the competitive landscape of mobile app development, user experience (UX) has emerged as a critical differentiator. React Native, with its robust framework and versatile capabilities, offers developers a powerful toolkit to create seamless and engaging user experiences. This blog post delves into the design principles and best practices in React Native app development, uncovering how developers can elevate user experience to new heights and drive success in the digital realm.

You can find the React Native documentation here and Flutter Documentation here.

Additionally, React Native, an extension of React.js, enables developers to create hybrid mobile applications with ease.

You don’t know what to do with your time while applying the 5th rule? Start small, tiny steps. If you can’t read much, start small, 15 minutes a day reading a technical article or even a book like Effective Java, by Joshua Bloch. You don’t like to read? Create small projects by using a framework you want to learn. Check for example: React framework.
