Code is Not Just Text

For too long, studying programming with flashcards has felt like reading a dictionary. Code snippets were either ugly, unformatted blocks of text or blurry screenshots that you couldn't copy-paste.

Today, we are changing that. We believe code is a first-class citizen in the learning process.

1. Native Syntax Highlighting

We have integrated a robust syntax highlighting engine directly into our flashcard renderer. Supporting over 100 languages, your snippets now look exactly like they do in your IDE.

// This is how code should look
async function masterAlgorithm(user) {
  if (user.usesFlashcardForge) {
    await user.levelUp("JavaScript");
    return "Mastery Achieved";
  }
}

Whether you are learning Python, Rust, TypeScript, or Go, your flashcards will respect the syntax, making pattern recognition faster and more natural.

2. Verified External Sandboxes

Learning to code requires doing, not just reading. We wanted you to be able to link directly to live coding environments without compromising security.

We have implemented a Strict Whitelist System that allows you to link directly to trusted coding sandboxes. When you see a blue link in a flashcard, you know it's safe.

Supported Platforms:

• JSFiddle (jsfiddle.net)
• CodePen (codepen.io)
• CodeSandbox (codesandbox.io)
• Replit (replit.com)
• StackBlitz (stackblitz.com)
• Glitch (glitch.com)

Any link outside of our verified whitelist is automatically rendered as plain text to protect you from malicious sites.

3. The Workflow

Imagine a flashcard that asks you to "Implement a Binary Search."

1. Front: The question and constraints.
2. Back: The solution in beautifully highlighted code.
3. Action: A direct link to a LeetCode problem or a CodePen where you can verify your solution instantly.

This is the future of technical mastery. Stop memorizing text. Start internalizing logic.
