Quick Intro

You must do TWO THINGS:

1. Code along with the examples. [ YOU MUST RITE TEH CODES ☠️ ]
2. Complete these exercises as you become able.

Before coding can become intellectual, it must become physical. You can only learn the code intuitively, to try to understand is to fail. To learn the patterns by trying things again and again is to succeed.

Data types

• Number
• Function
• String
• Boolean
• Array
• Object

Number

let a = 3;

let b = 1.5;

let c = a + b;

console.log(c); // 4.5

Now make your own example. Do it now. Try to break things.

---

Function

let add = (a, b) => {
  return a + b;
};

let sum = add(3, 1.5);

console.log(sum); // 4.5

Now run your own example. Right MEOW! Make mistakes.

---

String

let greeting = 'Hello';

let name = 'Charlie';

let message = greeting + ' ' + name;

console.log(message); // Hello Charlie

Now run your own example. Immediately! Do bad things.

---

Boolean

let feet = 2;

let isHuman = feet < 3;

if (isHuman) {
  console.log('Hi!');
}

Now run your own example. Without delay! Write the ugliest code.

---

Array

let alphabet = ['a', 'b', 'c'];

for (let letter of alphabet) {
  console.log(letter); // a b c
}

Now run your own example. Quickly! Make errors happen.

---

Object

let dictionary = {
  'you': 'toi',
  'me': 'moi',
  'him': 'lui',
  'her': 'elle'
};

let word = dictionary['you'];

console.log(word); // toi

Now run your own example. Quickly, before ze Germans get here. The code must become a neurological extension of your body.
