Guide to Data Types

1. String

• Use: used to represent text data

• Denoted by ' ' or " " marks.

• example: "Peach" or "(303)555-5555" or "colorless green ideas sleep furiously"

2. Integer

• Use: used to represent whole number data

• Can be +, -, or 0 & manipulated mathematically

• example: 1 or 1,375

3. Float

• Use: used to represent decimal point/fractional data

• Can be + or - & manipulated mathematically

• example: 3.141592 or -0.00001

4. Boolean

• Use: either True or False

• You can think of this like a light switch

// Useful symbols when working with type of data include: && || and ==

• example: True or False

5. Array

• Use: data structure that represents a group of things

• Typically, data within an array are all the same type

• example: ["The Shining", "It", "Pet Sematary", "Dr. Sleep"] or [2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37]

6. Hash/Object

• Use: used to represent a key-value pair of data.

• Similar to an array, except we are pairing data together

• example: {"March": 58, "April": 65, "May": 73}
