My loop fetches 20 user profiles one after another and takes 8 seconds. Node 20, ESM. How do I speed it up?

CLAUDE · WITH THIS SKILL You get: the cause in one line (awaits inside the loop run sequentially) -> a runnable ESM function that fires all fetches and awaits them with Promise.allSettled -> per-request error handling that keeps the successful profiles -> a one-line why on allSettled vs all -> a note on capping concurrency if the API rate-limits -> the single next action: swap the loop in and compare timings with console.time.

// qué incluye

What you're actually buying

Esta habilidad de Claude/ChatGPT es un programador en pareja de AI basado en JavaScript dentro de tu trabajo diario de programación: escribe funciones, módulos y scripts de Node ejecutables para el entorno de ejecución que indiques, reescribe esperas secuenciales lentas para convertirlas en flujos con Promise.all, revisa código pegado en busca de errores asíncronos y riesgos de XSS, diagnostica errores como «Cannot read properties of undefined» o conflictos entre ESM y CommonJS, y escribe pruebas de Jest o Vitest con mocks y temporizadores simulados.

Conoce el bucle de eventos, los cierres y la vinculación de this, los módulos ES, las API del navegador, los módulos principales de Node.js, npm y empaquetadores como Vite y esbuild, además de cómo confirmar una causa en DevTools. Es una herramienta de ayuda para tu trabajo con JavaScript, no una persona con un rol laboral, y no ejecuta ni implementa código por sí misma; te entrega el código y el comando para verificarlo.

Funciona de la misma manera en Claude, ChatGPT y Gemini. Una sola compra, descarga el archivo, instálalo en menos de 2 minutos y, después, pega tu fragmento de código o error para obtener una solución con el razonamiento.

# AI Skill for JavaScript
KissMySkills.com | Install: paste this whole file into Claude Projects (Project instructions), a custom GPT (Instructions), a Gemini Gem, or your AI's system prompt. Then just ask questions the way you normally would.

## Who you are
You are a senior JavaScript pair programmer sitting next to the user while they write, debug and ship JavaScript in the browser and in Node.js. You know the language and its quirks, the runtimes, the package ecosystem and the tooling, and you hand over code that runs, reviews that find real bugs, and explanations that make the event loop click. You are the helper inside the user's JavaScript work, not a job-role persona. Tone: direct, practical, code first.

## What you know about JavaScript
- Language: let and const scoping, closures, prototypes and classes, this binding, arrow functions, destructuring, spread and rest, optional ch

Preguntas sobre este producto

What does the AI Skill for JavaScript do?+

It turns Claude or ChatGPT into a JavaScript AI pair programmer that writes runnable code for browser and Node.js, fixes async and module problems, reviews your JavaScript for bugs and security issues, and writes Jest or Vitest tests.

Does it run or deploy my JavaScript for me?+

No. It does not execute anything. It gives you the JavaScript code, the config change or the DevTools steps, and tells you what to run to verify the result yourself.

Does it cover Node.js as well as browser JavaScript?+

Yes. It asks which runtime you target (browser, Node.js version, Deno or Bun) and which module system you use, then writes JavaScript that fits: fs and streams on Node, DOM and fetch in the browser.

Can it work with React, Vue or Express code?+

Yes, when you name the framework. It keeps plain JavaScript separate from framework patterns so you get idiomatic code for React, Vue, Svelte, Express or Fastify rather than a mix.

Which AI tools does this skill work with?+

Works with Claude (recommended), Claude Code, ChatGPT, Gemini and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results because it remembers your JavaScript runtime, framework and lint rules between chats.

Do I have to read it myself?+

No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.

Is this a physical book?+

No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
