React Native.

Write JavaScript and React to build apps for iOS, Android, and the web from a single code base.

According to Atwood's law, any application that can be written in JavaScript will eventually be written in JavaScript.

The first way JS developers tried to build mobile apps was

by wrapping their native applications in a sandbox browser called a WebView, using tools like

Apache Cordova and Adobe PhoneGap.

The philosophy is write once, run anywhere.

This works, but it can be hard to make a website feel like a true native experience.

React Native takes a different approach.

It feels just like

React DOM for the web, but instead of using HTML and the DOM as building blocks for the UI,

it uses the native components that you would find on iOS and Android.

The philosophy is learn once, write anywhere.

You can't just take your existing

React web app and upload it to the App Store,

but you can use the React skills you already have to build a native app without ever having to touch

Java or Objective -C.

Instead, you import building block components like button, switch, scroll view, and the most fundamental of which is view.

At runtime, it will use the true native component on the corresponding platform, like UI view, Android dot view, or div on the web.

It's like building three apps for the price of one, but in some cases, you may want a different visual experience based on the underlying OS.

The platform module allows you to check which platform you're on and render different components accordingly.

When it comes to visuals, there's no CSS in React Native.

Instead, every core component takes a style prop that can be customized with a style sheet constructed from JavaScript.

In development, it supports fast refresh, which means you can instantly see the changes you make to your code on any platform.

You may also want to tap into native features like the device camera, push notifications, and geolocation.

These concerns are handled by one of the most active open source communities on GitHub.

There's open source packages for almost everything that can be installed with NPM just like any other JavaScript project, and there's frameworks like

Expo that build on top of React Native Primitives to provide all the tooling required to ship your app to production.

You can use

React Native to build a complete mobile app or integrate it with existing iOS and Android projects.

It's not an all -or -nothing solution.

需要注意的发音

“sh” 和 “zh” 音: sheet /ʃit/, notification /ˌnoʊtɪfɪˈkeɪʃn̩/, refresh /ɹɪˈfɹɛʃ/
长单词——注意重音位置: fundamental /ˌfʌn.dəˈmɛn.təl/, developer /dɪˈvɛləpɚ/, accordingly /əˈkɔɹ.dɪŋ.li/, notification /ˌnoʊtɪfɪˈkeɪʃn̩/

中文母语者容易读错的音：

/v/ — 不要读成 /w/，上齿轻触下唇: developer /dɪˈvɛləpɚ/, java /ˈd͡ʒɑː.və/
词尾辅音 — 要读清楚，后面不要加元音: component /kəmˈpoʊ.nənt/, package /ˈpæk.ɪd͡ʒ/, installed /ɪnˈstɔːld/, sheet /ʃit/, framework /ˈfɹeɪm.wɜːk/
/r/ 和 /l/ 的区别: accordingly /əˈkɔɹ.dɪŋ.li/, scroll /skɹoʊl/

如何用这段视频练习

先完整听一遍视频，不要开口，记下不认识的单词。
先用 0.75 倍速逐句跟读，熟练之后再回到正常速度。
录下自己的声音并与原声对比，特别注意 component, package, skill 这类单词。

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
