Project Details

JavaScript implementation of an algorithm that simulates making change at a cash register, making exact change when possible.

The final project in this freeCodeCamp certification track is a little more involved than the other four. In accordance with the specifications, I implemented a series of algorithms in JavaScript to calculate a valid amount of change for some cash transaction. A price, a cash payment amount, and an initial cash register balance are expected as input.

The CodePen link above will open an in-browser code editor and console. Tinkering at the console will enable you to interface with the  checkCashRegister  function I implemented. Note that all other functions are designed as helper functions and are therefore not expected to be called directly.
