React ATM application

---

Let's practice modifying an existing codebase. This repository contains the code for existing ATM application using React. In it, you can currently deposit money into a checking account.

You'll be adding a few features to this:

• The ability to withdraw money
• Having a savings account as well as a checking account

In the end, your solution will look like this:

---

Setting up:

• Fork and then clone this repo

• Run npm install (or npm i for short!)

• To launch the app, run npm start.

• The code that's running is in the /src directory - that's what you need to change!

You can do the below tasks in any order you'd like.

Task:

Currently, you can see that there is a Checking account where a user can deposit money. Try it out - it works!

• Create a "Withdraw" button next to the "Deposit" button.
  • You should not be able to withdraw more than the current balance.
• Create a Savings account - another component of the same class.
  • It will have the same deposit (and eventual withdraw) functionality.
• You cannot type negative numbers in to either withdraw or deposit.

Hints:

Stuck on making a Savings account? Here's a hint:

The name prop being passed into Account is "Checking" - perhaps you can just call the component again for "Savings".

Stuck on making a Withdraw button? Here's a hint:

Functionality to withdraw money is quite similar to functionality for depositing money, except with subtraction instead of addition.

Stuck on limiting negative numbers? Here's a hint:

When a function checks if the input is a number (with isNaN), an || condition could be added to be sure the input is not less than 0.
