Practice Testing with Jest

Introduction

This project is part of The Odin Project focuses on practicing testing using Jest.

Capitalize Function
- A function that takes a string and returns it with the first character capitalized.
Reverse String Function
- A function that takes a string and returns it reversed.
Calculator Object
- An object that contains functions for the basic operations: add, subtract, divide, and multiply. Each of these functions should take two numbers and return the correct calculation.
Caesar Cipher Function
- A function that takes a string and a shift factor and returns it with each character “shifted”.
- Wraps from z to a. For example, caesarCipher('xyz', 3) should return 'abc'.
- Preserves case. The shifted lettercase should follow the original lettercase. For example, caesarCipher('HeLLo', 3) should return 'KhOOr'.
- Keeps punctuation unchanged. For example, caesarCipher('Hello, World!', 3) should return 'Khoor, Zruog!'.

Analyze Array Function

A function that takes an array of numbers and returns an object with the following properties: average, min, max, and length.

const object = analyzeArray([1, 8, 3, 4, 2, 6]);

object == {
   average: 4,
   min: 1,
   max: 8,
   length: 6
};
