There are at least 6 different data types

1. Strings
2. Integers
3. Floats
4. Boolean
5. Array
6. Extensions

Here is an example of each data type:

• String is text. Example is "hello" or 'hello' (don't forget the quotations, please).
• Integer is a whole number (positive or negative). Example is 10, 0, or -25.
• Float is a number with decimals (positive or negative). Example is 5.5 or -0.001.
• Boolean is a true or false value/indicator. An example is a conditional statement such as if x >= 5.
• Array is a collection of values. Example is formated as such [26,24,27] or ["a","b","c"]. It's best to have one data type within an array for coding simplicity (meaning to be able to manage/work with the values in an array) although it is possible to have multiple data types.
• Extension is data where pairing or coupling information is important. An example is as follows { "9th grade": 110, "10th grade": 125, "11th grade": 66, "12th grade": 70}. It's important in this instance to pair the grade (9th with the room of 110. Another example is { "Mod 0": "Tim and David", "Mod 1": "Mike and Sal", "Mod 2": "Brittany and Robbie" }

Here is a javascript code block with some data type examples.

var pizza = "the best food of all time";      //string example
var isHungry = true;
var number = 5;                               //integer example
// reassign number
console.log("number = "+number)
number = 4;                                   //integer example
console.log("number reassigned to "+number)
var teachers = ['Ellen','Robert','David']     //array example
console.log(teachers)
var pizzaType = "Pepperoni pizza is"
var output = pizzaType + " " + pizza
console.log(output)
var number2 = 5                               //integer example
number * number2
console.log(number+"*"+number2+"="+number * number2)

Here's a useful image of javascript data types.
