Write a function that converts an object into an array, where each element represents a key-value pair in the form of an array.

Examples

toArray({ a: 1, b: 2 }) ➞ [["a", 1], ["b", 2]]

toArray({ shrimp: 15, tots: 12 }) ➞ [["shrimp", 15], ["tots", 12]]

toArray({}) ➞ []

Notes

Return an empty array if the object is empty.
