Hello There 👋
Installation
For each programs, make sure you are downloading a version that works for your system
Install vscode
- Download the installer https://code.visualstudio.com/download
If you already have and love a code editor, feel free to use it, but keep in mind that we will use VSCode as reference
VSCode is a code editor, it will give you an interface to write, test and submit your code.
Install git
- Download the installer https://git-scm.com/downloads
- While installing, Git will ask a bunch of questions, it is recommended to change those:
- Choosing the default editor (pick VSCode)
- Configuring the line ending conversions (Choose : Checkout as-is, commit Unix-style line endings)
- Otherwise stick with the defaults unless you know what you are doing.
Git is a versioning tool, we use it to upload your solutions on the school server.
Install nodejs
- Download the installer https://nodejs.org/en/download/current/
NodeJS will allow to execute JavaScript code outside of the browser, useful for testing your code.
Values
There are 3 types of values, and they can model the WORLD !
(In the end it's all 1
's and 0
's for the computer), but us, humans, need
an easier way of representing stuff.
We can all agree that
11010001100101110110011011001101111
is not a very friendly way to say'hello'
!
Numbers 🔢
- Whole numbers:
1
,23
,232139283
- Negative numbers are prefixed with
-
:-1
,-1231
- Decimal numbers:
3.14
,-2.53343
etc...
Use them for quantities like in daily life.
Booleans ✖️ / ✔️
- Something is
true
- or
false
They represent a truth, an answer to a closed-ended question (anything that can be answered with yes or no):
- Is paris the capital of France ?
true
- Are you born before 1723 ?
false
- Is your screen turned on ?
true
(most likely)
Strings 🆒
'Hello'
'This is some text'
A string is a sequence of characters used to represent text, it needs
delimiters to define its begining and end.
Delimiters are matching quotes, either `
, "
or '
.
Using console.log
To display output from a script into a console, use the function console.log
:
console.log() // <- will show an empty line
Add any value between the parentheses to see it appear when the script is executed.
It is very important to use this often to validate that our code is valid. The more it is tested, the easier it is to understand what's going on in the code !
In doubt,
console.log
everything, don't be shy, they are for free.
Instructions
Once you have installed and configured the necessary tools,
create in your Gitea account the repository named ((ROOT))
with a hello-there.js
JS file that is a program that displays:
- the exact text
Hello There !
- any
Number
- and a
Boolean
.
In order to work in your repository and put files in it, you need to clone it first.
If your username was choumi
this is the command that will need to be used:
git clone https://((DOMAIN))/git/choumi/((ROOT)).git
To execute it, open a Unix shell (e.g. Git Bash on Windows), you are going to type commands in it. This command needs to be adapted with your own username.
Don't forget to commit and push the file to the servers
Optional (git setting to avoid typing the password every time)
The ((ROOT))
repository will be the folder where all the exercises must be uploaded.
In order to avoid writing your username and password every time you git push
an exercise,
tell Git to remember your password (like a web browser would) with the below command:
git config --global credential.helper store
Recommendation
Videos designed to give hints are assigned to each quest. It is strongly suggested to watch them as you go.
