We recommend you do this if you spend a lot of time on your mobile while learning. If you are using a laptop / computer, we recommend using the Google Chrome setup described below.
Chrome is available for download on its website Chrome Web Browser. Installation on Windows and OSX systems is pretty straightforward, just double-click the downloaded file to start installation.
For linux systems, you get an option of downloading a .deb or a .rpm package.
Ubuntu or Debian based distributions
Download the .deb package to your Downloads folder. Open up a terminal by pressing Ctrl + Alt + T and enter the following commands.
cd ~/Downloads/sudo dpkg -i google-chrome-stable_current_*.deb
Fedora, openSUSE or RedHat based distributions
Download the .rpm package to your Downloads folder. Open up a terminal by pressing Ctrl + Alt + T and enter the following commands.
cd ~/Downloads/sudo yum install ./google-chrome-stable_current_*.rpm
If you are using any other distribution, go to Linux Chromium Packages, to find a suitable package. Once you are done with the installation, it's time to get started with the console.
Click on the Console tab. You should see a small window like this.
You can also use the Keyboard shortcut Ctrl + Shift + J (Cmd + Shift + J on OSX) to start the console.
If it still shows some random error messages then go to a new tab and open the console.
Once you're ready you'll see a little arrow (>) with a text field. This is where you type your command. The console also gives suggestions for possible commands and keywords as you are typing. You can press Tab to autocomplete a command.
The console can be used for many purposes. For now, let's use it as a simple calculator. Try typing 1 + 6 and press Enter and see what you get.
It turns out that the console can be used for a lot more that just basic calculations. Move on to the next tutorial to learn more!
