Introduction
Are you interested in creating a calculator using JavaScript? Look no further! In this blog post, we will guide you through the step-by-step process of building a calculator from scratch, complete with HTML, JavaScript code blocks, and a live demo to showcase the final result.
Step 1: Setting up the HTML Structure
First, let’s start by setting up the HTML structure for our calculator. Create a <div> element with an id of “calculator” to serve as the container for our calculator.
<div id="calculator">
</div>
Step 2: Styling the Calculator
Next, let’s add some CSS to style our calculator. You can customize the appearance to match your preferences. For simplicity, we will use a basic layout with buttons for numbers and operators.
#calculator {
/* Add CSS styling here */
}
Step 3: Implementing the JavaScript Logic
Now, let’s dive into the JavaScript part. Create a new JavaScript file and link it to your HTML document using the <script> tag. Inside the JavaScript file, we will define functions to handle the calculator’s operations.

Step 4: Handling User Input
To make our calculator functional, we need to handle user input. We can achieve this by adding event listeners to the calculator buttons. When a button is clicked, the corresponding function will be executed.
// Event listeners for button clicks will be added here
Step 5: Displaying the Result
Lastly, we need to display the result of our calculations. We can create a text input field or a <span> element to show the output. By updating the value or innerHTML of this element, we can display the calculated result.
