Lab: 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:

Clone this repo, and run npm install. To launch the app, run npm start.
The code that's running is in the /src directory - that's what you need to change!
The /solution_src directory is just that - the solution - don't look before giving this your best shot!

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.

Solution

Solution code is provided in the solution_src folder of this repository. Please give this your best go before looking!
