Build a JavaScript Calculator

Objective

Build an app that is functionally similar to this: https://codepen.io/FreeCodeCamp/full/rLJZrA/.

Requirements

• User Story: I can add, subtract, multiply and divide two numbers.

• User Story: I can clear the input field with a clear button.

• User Story: I can keep chaining mathematical operations together until I hit the equal button, and the calculator will tell me the correct output.
