-There are 5 different types of data. The compiler/computer interprets all the variables we make as one of those datatypes.
-(https://javascript.info/types)
+In JavaScript, a primitive (primitive value, primitive data type) is data that is not an object and has no methods. There are 7 primitive data types: `string`, `number`, `bigint`, `boolean`, `null`, `undefined`, and `symbol`.
 
 Boolean — true or false
 Null — no value
 Undefined — a declared variable but hasn’t been given a value
 Number — integers, floats, etc
 String — an array of characters i.e words
-?? Symbol — a unique value that's not equal to any other value ??
+Symbol — a unique value that's not equal to any other value (not used during HYF)
 
 ### Example
 
 - `string`, e.g. "HackYourFuture"
 - `number`, e.g. 5, or 10.6
 - `boolean`, e.g. `true` or `false`
-- `array`\*, e.g. `[1, 2, 3]` or `['what', 'is', 'your', 'name']`
-- `null`
-- `undefined`
-  The values `null` and `undefined` are very similar in JavaScript, but they behave a bit differently. The difference is that `null` always has type "object", and `undefined` always has type "undefined".
+- `array`, e.g. `[1, 2, 3]` or `['what', 'is', 'your', 'name']`
+- `null` \*
+- `undefined` \*
+- `symbol` e.g. `new Symbol('example')`
 
+\* The values `null` and `undefined` are very similar in JavaScript, but they behave a bit differently. The difference is that `null` always has type "object", and `undefined` always has type "undefined".
 Whenever you declare a variable (using `let`), but you don't set a value, the variable will become `undefined`. JavaScript will never make a variable `null` unless you explicitly program it.

-let x = 5;

 In this way we can store a lot of data in a compact way, while the computer/compiler knows how to interpret the 1's and 0's/
 
 ## 5. The compound data types (object, array)
 
 ### Explanation
 
-- Object key / value
-- Array numeric key value
-- Array ordered
-- Object not ordered
+Pieces of information often form a group. For example the names of all the students in this class can be grouped together
+as a list. In JavaScript lists are stored in a datatype called an `Array`.
+
+Another way pieces of information can form a group are multiple properties of the same thing. For example the dimensions
+of this room: length, width, height. These groups of information are stored in a datatype called an `Object`.
 
 ### Example
 
-- `array`\*, e.g. `[1, 2, 3]` or `['what', 'is', 'your', 'name']`
-- `object`, e.g. `{name: 'John', age: 24}`, or the special object `null`
+- `array`\*, e.g. `[1, 2, 3]` or `['Gijs', 'Jim', 'Noer', 'Wouter']`
+- `object`, e.g. `{name: 'Wilgert', shoeSize: 42}`, or the special object `null`
 
 ### Exercise
 
 1. Create a list of your favorite types of food/dishes like this:
 
 ```js
-['Chocolate', 'Risotto', 'Tuna melt'];
+const foods = ['Chocolate', 'Risotto', 'Tuna melt'];
 ```
 
 2. Create an object that contains the properties of your town/city like this:
 
 ```js
-{
+const city = {
   name: 'Huizen',
   province: 'Noord-Holland',
-  citizens: 50000
-}
+  population: 50000,
+  capital: false,
+};
