Building a Simple Wendy’s Menu Viewer with JavaScript

Building a Simple Wendy’s Menu Viewer Using JavaScript (2025)

When working on frontend projects, I often build small real-world examples to practice API handling, rendering dynamic data, and structuring UI components. A fast-food menu is a great use case because it involves categories, pricing, and conditional rendering.

In this post, I will show how to build a simple Wendy’s menu viewer using plain JavaScript. The goal is not to scrape data, but to demonstrate how menu-style data can be structured and displayed cleanly.

Step 1: Define Menu Data Structure

First, we define a basic menu object. In a real application, this data could come from an API or CMS.

const wendysMenu = {
breakfast: [
{ name: "Breakfast Baconator", price: 4.99 },
{ name: "Honey Butter Chicken Biscuit", price: 3.79 }
],
lunch: [
{ name: "Dave’s Single", price: 5.49 },
{ name: "Spicy Chicken Sandwich", price: 5.29 }
],
value: [
{ name: "Jr. Cheeseburger", price: 2.19 },
{ name: "4 Pc Nuggets", price: 1.99 }
]
};

This structure keeps categories separate and makes it easier to loop through them dynamically.

Step 2: Create a Render Function

Next, we write a function that renders menu items into the DOM.

function renderMenu(category) {
const container = document.getElementById("menu");
container.innerHTML = "";

wendysMenu[category].forEach(item => {
const div = document.createElement("div");
div.className = "menu-item";
div.innerHTML = <strong>${item.name}</strong> - $${item.price};
container.appendChild(div);
});
}

This approach allows us to switch categories without reloading the page.

Step 3: Add Category Controls

Now we add simple buttons to toggle between breakfast, lunch, and value items.

Breakfast
Lunch
Value Menu

With this setup, clicking a button updates the displayed menu instantly.

Step 4: Styling (Optional)

Basic styling improves readability without adding complexity.

.menu-item {
padding: 8px 0;
border-bottom: 1px solid #eee;
font-family: Arial, sans-serif;
}

Why This Example Works Well for Practice

This small project demonstrates several useful frontend concepts:

Object-based data modeling

DOM manipulation

Event-driven rendering

Clean separation of data and UI logic

For developers who want to expand this further, the next steps could include filtering, search, or connecting to a real data source.

If you want to compare how this structured data aligns with real menu categories, reviewing the Wendy’s official menu beforehand can help ensure realistic grouping and naming conventions.

Final Thoughts

Building simple projects around real-world data is an effective way to sharpen frontend skills. A menu viewer like this is lightweight, practical, and easy to extend into something more advanced.

Whether you are learning JavaScript fundamentals or prototyping UI components, examples like this keep practice both realistic and engaging.
