Truly Native:

Most apps written with JavaScript use Cordova , or a framework that builds there on , also because the popular Ionic or Sencha Touch frameworks . But no Cordova App will ever get the texture of a true native App.

Scrolling, keyboard behavior and navigation can bring frustrating experiences if they are doing not work needless to say.

Even though JavaScript remains written in React Native, the components are rendered as Native Platform widgets. And if you’ve written apps in Java or Objective C, you’ll spot some React Native components directly .

Ease of learning

One of React’s biggest strengths is reading comprehension, even for programmers who haven’t worked with it yet. Many other frameworks first require you to find out an extended list of concepts that don’t have anything to try to to with the language building blocks.

As an example, let’s compare the difference between rendering an inventory of friends in React Native and Ionic (Angular JS)

Ionic uses ngRepeat Directiv.

Let’s assume we have an order for friends. Each field contains the following fields: first_name, last_name and is_online. But we only want to show them, which are currently online. Here is our controller:

function FriendCtrl ($ scope) {
$ scope.friends = [
{
first_name:, John ‘,
last_name: ‘Doe’,
is_online: true,
},
{
first_name:, Jane ‘,
last_name: ‘Doe’,
is_online: true,
},
{
first_name:, Foo ‘,
last_name:, Bar ‘,
is_online: false,
}
];
}

And here is our view:

<div ng-controller = “FriendCtrl”>
<Ul>
<li ng-repeat = “friend in friends | filter: {is_online: true} “>
{{friend.last_name}}, {{friend.first_name}}
</ Li>
</ Ul>
</ Div>

But if you are unfamiliar with Ionic / Angular JS, you can directly ask yourself a few questions.What is $ scope? What is the syntax for a filter? And how can I add more behaviors, such as sorting the friends list?

With React Native, one can revert to already existing knowledge of the language, using the filter and map functions.

const DemoComponent = React.createClass ({
render () {
const friends = [
{
first_name:, John ‘,
last_name: ‘Doe’,
is_online: true,
},
{
first_name:, Jane ‘,
last_name: ‘Doe’,
is_online: true,
},
{
first_name:, Foo ‘,
last_name:, Bar ‘,
is_online: false,
}
];
return (
<View>
{friends
.filter (f => f.is_online)
.map (f => <view> {f.last_name}, {f.first_name} </ view>)}
</ View>
);
}
});

Since the most part is normal JavaScript and only a couple of small parts are different, React Native is simpler to know for all programmers and is straightforward to use even for beginners.

React is additionally a really good learning tool, if you are doing not skills to use Map or Filter. React also brings you closer to these functions.

Developer experiences

“Happy developers are productive developers,” and React Native has a good developer environment. Instead of constantly expecting the code to compile and restart the app whenever you create alittle change, your React Native Codebase changes within the running app.

And if you’ve been working with JavaScript, you almost certainly also know the Chrome Developer Tools.

While running React Native in Developer mode, you’ll tie this to your desktop Chrome browser, so you’ll use your debugger tools and profiling tools at an equivalent time. React uses native flexbox for the layout .

While every layout engine is different, React Native’s support for flexbox means you’ll use an equivalent layout code for Android, iOS and web.
