O Que Você Pode Construir
Modern JavaScript Migration
A developer needs to migrate legacy JavaScript code to modern ES6+ standards with improved patterns and better error handling.
Async Debugging
A engineer faces race conditions or promise rejection issues in their Node.js application and needs expert debugging strategies.
Cross-Platform Compatibility
A team building browser applications needs guidance on polyfills, bundle optimization, and cross-browser compatibility.
Tente Estes Prompts
Convert this legacy JavaScript code to modern ES6+ syntax. Use destructuring, arrow functions, and const/let appropriately.
Help debug this async code. It has a race condition where the promise resolves before the event handler completes.
Profile this JavaScript code for performance bottlenecks. Focus on event loop blocking and memory usage in Node.js.
Design a polyfill strategy for this ES6+ code. Target browsers: Chrome 90+, Safari 14+, Firefox 88+.
Melhores Práticas
- Always use async/await instead of promise chains for better readability and error handling
- Handle errors at appropriate boundaries with try/catch blocks rather than per-operation
- Consider bundle size impact when using modern features in browser environments
Evitar
- Avoid mixing callbacks with promises in the same code path as it creates error handling complexity
- Do not use Promise.all() when operations must complete sequentially, use for...of with await instead
- Never ignore promise rejections by omitting catch handlers or .catch() blocks
