Code example

Request

curl -X POST https://instantapis.net/api/v1/generate \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "task": "code",
    "input": "Create a TypeScript function that debounces any callback with generics support and proper cleanup",

    }
  }'

Response

{
  "success": true,
  "data": {
    "code": "function debounce<T extends (...args: any[]) => any>(\n  fn: T,\n  delay: number\n): (...args: Parameters<T>) => void {\n  let timeoutId: ReturnType<typeof setTimeout>;\n  return (...args: Parameters<T>) => {\n    clearTimeout(timeoutId);\n    timeoutId = setTimeout(() => fn(...args), delay);\n  };\n}",
    "language": "typescript",
    "explanation": "Generic debounce function that preserves the original function's parameter types using Parameters<T>. Uses clearTimeout for cleanup on each invocation."
