💻 Developers build software using code and programming languages.

What Do Developers Do?

• 1️⃣ Writing Code – Using programming languages to build apps, games, and websites.
• ️Example A web developer writes HTML, CSS, and JavaScript to make a website.
• 2️⃣ Debugging (Fixing Errors) – Finding and fixing errors in software.
• Example: If a button on an app doesn’t work, a developer finds out why and fixes it.
• 3️⃣ Testing Software – Ensuring software works before launch.
• Example: A developer tests a banking app to check if transactions work smoothly.
• 4️⃣ Maintaining and Updating Software – Improving features and fixing bugs.
• Example: WhatsApp updates its app with new emojis and better security.
