Examples

Learn how to use ExplainThisCode effectively with practical examples and tutorials. From basic usage to advanced integrations, we've got you covered.

Who Are These Examples For?

These examples are written for developers of all skill levels. If you are just getting started, the Basic Usage section walks you through your first explanation step by step. Experienced developers can skip ahead to Advanced Usage to learn about batch processing, custom prompts, and fine-tuned analysis modes.

Team leads and DevOps engineers will find the Integration examples especially useful — they show how to connect the platform to GitHub Actions, VS Code, and other tools you already use every day.

Quick-Start Hint

The fastest way to try our tool is to paste a short snippet into the Explain page and choose a mode. You will get a detailed breakdown in seconds. Once you see how it works, come back here to explore language-specific examples and deeper analysis options.

Basic Usage

Learn the fundamentals with simple, hands-on examples

Advanced Usage

Explore advanced features like custom prompts and batch processing

Integration

Integrate with your IDE, CI/CD, and development tools

Explaining a React Component

Here's how you might use the analyzer to understand a React component:

// Paste this code into the Explain page:
const Counter = () => {
  const [count, setCount] = useState(0);

  return (
    <button onClick={() => setCount(c => c + 1)}>
      Count: {count}
    </button>
  );
};

Select "Beginner" mode to get a detailed explanation of React hooks, state management, and event handling.

Understanding an Algorithm

Use "Performance" mode to analyze the time and space complexity of algorithms:

function binarySearch(arr, target) {
  let left = 0, right = arr.length - 1;
  while (left <= right) {
    const mid = Math.floor((left + right) / 2);
    if (arr[mid] === target) return mid;
    if (arr[mid] < target) left = mid + 1;
    else right = mid - 1;
  }
  return -1;
}

Security Analysis

Use "Security" mode to identify potential vulnerabilities in your code:

app.get('/user/:id', (req, res) => {
  const query = `SELECT * FROM users WHERE id = ${req.params.id}`;
  db.query(query, (err, result) => res.json(result));
});

The analyzer will identify the SQL injection vulnerability and suggest parameterized queries.
