**Angular** is a TypeScript-based, open-source web application framework led by the Angular Team at Google. Angular is a complete rewrite from the team that built AngularJS.

# Pre-requisites

Before starting with Angular, you need to make sure that you already have **Node.js** installed in your system. If you do not, run the following commands on the terminal to add Node.js PPA in your Ubuntu system and install it:
```Ubuntu
sudo apt-get install software-properties-common
```
```Ubuntu
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
```
```Ubuntu
sudo apt-get install nodejs
```


To verify the installation, view the version of Node.js installed in your system with the following command:
```Ubunut
node --version
```

# Install Angular

After you have installed Node.js on your system, use the following commands to install the Angular CLI tool on your system:

```Ubuntu
npm install -g @angular/cli
```
`npm` is the `n`ode `p`ackage `m`anager  used to install the Angular command-line interface on a system. 

> The `-g` flag will install the Angular CLI tool globally so that it will be accessible to all users and applications on the system.



To verify the installation, check the version of Angular installed in your system using the `ng` command in Angular CLI:

```Ubuntu
ng --version
```

How to install Angular on Ubuntu

Install Node.js on Ubuntu, then use npm to globally install the Angular CLI tool with `npm install -g @angular/cli`. Verify installations using `node --version` and `ng --version`.
