Create a function that returns the data type of a given variable. These are the eight data types this challenge will be testing for:

• Array
• Object
• String
• Number
• Boolean
• Null
• Undefined
• Date

Examples

dataType([1, 2, 3, 4]) ➞ "array"

dataType(new Date()) ➞ "date"

Notes

Return the name of the data type as a lowercase string.
