|
|
|
|
|
|
|
|
|
|
|
|
### 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`:
|
|
|
|
|
|
|
|
|
|
|
|
```js
|
|
|
|
|
|
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 a `git` 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`.
|
|
|
|
|
|
|
|
|
|
|
|
> Don't forget to commit and push the file to the servers
|
|
|
|
|
|
|
|
|
|
|
|
