Components this. Components that. At first, I thought components were something unique to React. But after spending more time with vanilla JavaScript, I realized something. **The mindset behind React components already exists in JavaScript.** React didn't invent reusability—it simply gave it a better structure. If you're planning to learn React after JavaScript, there's one habit worth building now: > **Write reusable code.** --- ## Why Reusability Matters Imagine you're building a dashboard. It has five buttons. Every button shares the same styling and almost the same behavior. One approach would be to copy and paste the same code five times. It works... Until you want to change something. Now you're editing five different places. Maybe you decide to change the button color. Or the padding. Or add an icon. Now every copy needs to be updated. This is where reusable code shines. Write it once. Use it everywhere. Besides saving time, reusable code makes your projects: - Easier to maintain - Easier to debug - Easier to extend - Easier for other developers to understand --- ## JavaScript Already Supports This When people hear the word **component**, they immediately think of React. But JavaScript has supported reusable logic for years through functions. For example: ```javascript function createButton(text) { const button = document.createElement("button"); button.textContent = text; button.className = "btn"; return button; } ``` Instead of writing this repeatedly: ```javascript const saveBtn = document.createElement("button"); saveBtn.textContent = "Save"; const deleteBtn = document.createElement("button"); deleteBtn.textContent = "Delete"; const cancelBtn = document.createElement("button"); cancelBtn.textContent = "Cancel"; ``` You simply reuse your function: ```javascript document.body.append( createButton("Save"), createButton("Delete"), createButton("Cancel") ); ``` One function. Multiple buttons. Same logic. --- ## This Is The Mindset React Builds On Now look at React. ```jsx
