// Simple short id — not cryptographically secure, but okay for UI keys
function uniqueId() {
  // toString(36) makes it shorter (0-9a-z)
  return Math.random().toString(36).substring(2, 10);
}

// Use timestamp + random to reduce collision probability
function uniqueIdSafe() {
  return `${Date.now().toString(36)}-${Math.random().toString(36).substring(2, 8)}`;
}

// Node/browser crypto (secure)
function uniqueIdCrypto() {
  // browser: crypto.getRandomValues; Node: require('crypto').randomBytes
  return crypto.randomUUID(); // modern API (UUID v4), if available
}

// Usage:

console.log(uniqueId());         // ex: "k9x3f8q0"
console.log(uniqueIdSafe());     // ex: "l8k3x-9f2t3p"
console.log(uniqueIdCrypto());
