# This is a Expo Framework

Expo is a framework and a platform for universal React Applications. 
It is a set of tools and services built around React Native and native platforms that help you develop, build, deploy,
and quickly iterate on iOS, Android, and web Apps from the same JavaScript/TypeScript codebase.

# Requirements

- Node.js LTS release or greater
- Git
- Watchman for macOS users

# Recommended Tools

- VSCode Editor
- Yarn
- Windows users: PowerShell or Bash via WS

# Installing Expo CLI

```bash
 # install the command line tools
 npm install --global expo-cli
```

## Getting Started 

Create a new app:
At this point we should have Expo CLI installed on our development machine and the Expo Go App on an iOS or Android physical device or emulator.
If not, go back to the Installation guide before proceeding.

# Initializing the project

```bash
# Create a project named my-app.
# Select the "blank" templata when promped
expo init my-app

# Navigate to the project directory
cd my-app
```

First, run the development server:

```bash
expo start
# or
npm start
```

JavaScript powers the web - it's **the** most important programming language you need to know as a web developer.

## Exempel 1

For example, We have an array of different objects that can weigh the same or different and are spaced apart from us.
The customer wants the lightest and closest object.

```js
object.sort((a,b)=>a.weigh - b.weigh)

    const lightest=(object[0].weigh);
    let sortDistance=(object[0].distance);        

    for (let i = 0; i< object.length; i++) {      
      if (lightest === object[i].weigh && sortDistance > object[i].distance){
         sortDistance = object[i].distance;
         sortObject.unshift(object[i]);
      }else{
         sortObject.push(object[i]);
      }
    }
```

## Description

Nest is a framework for building efficient, scalable [Node.js](http://nodejs.org) server-side applications. It uses modern JavaScript, is built with  [TypeScript](http://www.typescriptlang.org) preserves compatibility with pure JavaScript and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).

Under the hood, Nest makes use of [Express](https://expressjs.com/), but also, provides compatibility with a wide range of other libraries, like e.g. [Fastify](https://github.com/fastify/fastify), allowing for easy use of the myriad third-party plugins which are available.

## Installation

```js
$ npm install
```

## Getting Started

Setting up a new project is quite simple. With npm installed, you can create a new Nest project with the following commands in your OS terminal:

```js
$ npm i -g @nestjs/cli
$ nest new project-name
```

## Running the app

```js
# development
$ npm run start

# watch mode
$ npm run start:dev

# production mode
$ npm run start:prod
```

## Test

```js
# unit tests
$ npm run test

# e2e tests
$ npm run test:e2e

# test coverage
$ npm run test:cov
```

## Support

Nest is an MIT-licensed open source project. It can grow thanks to the sponsors and support by the amazing backers. If you'd like to join them, please [read more here](https://opencollective.com/nest).

Getting Started With NestJS

# This is a NextJS
NextJS is a **framework for ReactJS**.

Wait a second ... a "framework" for React? Isn't React itself already a framework for JavaScript?

Well ... first of all, React is a "library" for JavaScript. That seems to be important for some people.

Not for me, but still, there is a valid point: React already is a framework / library for JavaScript. So it's already an extra layer on top of JS.

## Getting Started

Create Next App:

```bash
npx create-next-app
# or
yarn create next-app
```

First, run the development server:

```bash
npm run dev
# or
yarn dev
```

Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.

You can start editing the page by modifying `pages/index.js`. The page auto-updates as you edit the file.

[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on [http://localhost:3000/api/hello](http://localhost:3000/api/hello). This endpoint can be edited in `pages/api/hello.js`.

The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.

## Why would we then need NextJS?

Because NextJS makes building React apps easier - especially React apps that should have server-side rendering (though it does way more than just take care of that).

In this article, we'll dive into the core concepts and features NextJS has to offer:

- File-based Routing
- Built-in Page Pre-rendering
- Rich Data Fetching Capabilities
- Image Optimization
- Much More

## File-based Routing

## Learn More

To learn more about Next.js, take a look at the following resources:

- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.

You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!

## Deploy on Vercel

The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.

Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
