1
React Native.
2
Write JavaScript and React to build apps for iOS, Android, and the web from a single code base.
3
According to Atwood's law, any application that can be written in JavaScript will eventually be written in JavaScript.
4
The first way JS developers tried to build mobile apps was
5
by wrapping their native applications in a sandbox browser called a WebView, using tools like
6
Apache Cordova and Adobe PhoneGap.
7
The philosophy is write once, run anywhere.
8
This works, but it can be hard to make a website feel like a true native experience.
9
React Native takes a different approach.
10
It feels just like
11
React DOM for the web, but instead of using HTML and the DOM as building blocks for the UI,
12
it uses the native components that you would find on iOS and Android.
13
The philosophy is learn once, write anywhere.
14
You can't just take your existing
15
React web app and upload it to the App Store,
16
but you can use the React skills you already have to build a native app without ever having to touch
17
Java or Objective -C.
18
Instead, you import building block components like button, switch, scroll view, and the most fundamental of which is view.
19
At runtime, it will use the true native component on the corresponding platform, like UI view, Android dot view, or div on the web.
20
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.
21
The platform module allows you to check which platform you're on and render different components accordingly.
22
When it comes to visuals, there's no CSS in React Native.
23
Instead, every core component takes a style prop that can be customized with a style sheet constructed from JavaScript.
24
In development, it supports fast refresh, which means you can instantly see the changes you make to your code on any platform.
25
You may also want to tap into native features like the device camera, push notifications, and geolocation.
26
These concerns are handled by one of the most active open source communities on GitHub.
27
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
28
Expo that build on top of React Native Primitives to provide all the tooling required to ship your app to production.
29
You can use
30
React Native to build a complete mobile app or integrate it with existing iOS and Android projects.
31
It's not an all -or -nothing solution.
32
This has been React Native in 100 seconds.

Vocabulary and speaking notes for this lesson

This speaking lesson is built on the video “React Native in 100 Seconds”. The speaker keeps coming back to these words: native, React, app, Javascript, component. This video has 35 sentences and 473 words to shadow. The speech runs for 2:17. The speaker talks fast, about 208 words per minute, so expect linked and reduced sounds. Only 79% of the words are among the 3,000 most common in English, so the vocabulary is demanding.

מהי טכניקת השאדואינג?

שאדואינג היא טכניקת למידת שפה מבוססת מדע שפותחה במקור להכשרת מתורגמנים מקצועיים ופופולרית על ידי הפוליגלוט ד"ר אלכסנדר ארגואלס. השיטה פשוטה אך עוצמתית: אתה מקשיב לאודיו באנגלית ילידית וחוזר עליו בקול רם מיד — כמו צל העוקב אחרי הדובר עם עיכוב של 1–2 שניות בלבד. בניגוד להאזנה פסיבית או תרגילי דקדוק, שאדואינג מכריח את המוח והשרירים בפה לעבד ולשחזר דפוסי דיבור אמיתיים בו זמנית. מחקרים מראים שזה משפר משמעותית את דיוק ההגייה, האינטונציה, הקצב, הדיבור המחובר, הבנת השמיעה ושטף הדיבור — מה שהופך אותו לאחת השיטות היעילות ביותר להכנה לIELTS Speaking ולתקשורת באנגלית בעולם האמיתי.
