Final Project: Expense Tracker

Final Project — You've made it to the end!

Build a Console Expense Tracker

This is your capstone! Bring together everything you've learned — variables, arrays, loops, conditionals, and functions — to build a working expense tracker in JavaScript.

YOUR TASK

Create a program that:

Stores expenses in an array (at least 3 values)
Has an addExpense(amount) function that pushes to the array
Has a getTotal() function that loops through the array and returns the sum
Has a showExpenses() function that logs each expense
Calls all three functions and logs the total

Use functions to keep everything clean and reusable.

Need a hint?

Structure to follow:
1. const expenses = [];
2. function addExpense(amount) {'{'} expenses.push(amount); {'}'}
3. Add expenses: addExpense(20); addExpense(30);
4. function getTotal() {'{'}
  let total = 0;
  for (let i = 0; i < expenses.length; i++) {'{'}
    total += expenses[i];
  {'}'}
  return total;
{'}'}
5. function showExpenses() {'{'}
  for (let i = 0; i < expenses.length; i++) {'{'}
    console.log("Expense: " + expenses[i]);
  {'}'}
{'}'}
6. showExpenses();
7. console.log("Total: " + getTotal());

Example (expenses: 20, 30):

Expense: 20
Expense: 30
Total: 50
