How to Create a Smart Budgeting App Using JavaScript

Welcome to our guide on developing a smart budgeting application that predicts expense locations using the KNN (K-nearest neighbors) algorithm. This application is a fun experiment in machine learning that you can implement right in your browser. Let’s dive into the process step by step!

Introduction to the Budget App

The Budget app is a JavaScript project that uses simple machine learning techniques to forecast where your purchases are being made based on several factors, including:

• Day of the week
• Hour of the day
• Value of the expense

This app might not be robust or reliable, but it serves as an excellent proof of concept following a machine learning lesson. Bonus: it can also be added to your mobile device as a web app!

How It Works

Imagine that your budgeting app is like a map that doesn’t just tell you where you are but also predicts where you’re heading based on your past travels.

Let’s break down the KNN algorithm using a road trip analogy:

const location = KNN(expenseData, newExpense);

In our analogy, when you decide to stop for gas, the app calculates the closest gas stations based on the historical data of where you typically make purchases. It looks at your previous stops (like gas stations) and decides the most likely location where you might spend your money next based on when and how much you usually spend.

So hand in hand, your expenses and habits build an accurate picture, much like the navigational system adjusts its course based on your travel history!

Setting Up Your Budget App

Here’s a simple guide to get your app up and running:

1. Visit the online version of the app hosted here: Budget App
2. Clone the repository to your local machine to modify it as per your requirements.
3. Implement the KNN algorithm to your data by utilizing JavaScript fits your specifications for expense tracking.
4. Make sure to store your data using localStorage for simplicity:

localStorage.setItem("expenses", JSON.stringify(expenseData));

How to Translate the App

To make the app multilingual, you can follow these steps:

1. Make a copy of the en.json file.
2. Translate the sentences into your desired language in the new JSON file.
3. In jsmain.js, replace the variable langSetting to point to the file you made:

let langSetting = 'yourTranslatedFile.json';

Troubleshooting Ideas

If you encounter any issues while building or using the app, consider these troubleshooting steps:

• If the app crashes, check your console for any JavaScript errors affecting functionality.
• Ensure your localStorage is not full, as this can lead to issues with storing expense data.
• If the translations aren’t displaying correctly, verify that your JSON syntax matches the expected structure.
