JavaScript API Call: fetch, Axios, TanStack Query & ky
Most JavaScript API call guides are still in 2023 — fetch + Axios + XMLHttpRequest + jQuery. The real modern comparison is fetch + async/await + AbortController (the modern baseline), Axios (still popular for interceptors), TanStack Query (the React standard), and ky/ofetch (lightweight replacements). Plus the 4xx/5xx error gotcha fetch doesn't reject for, the Axios CancelToken deprecation, type-safe APIs with Zod, and FormData uploads done right.

YouTube Data API in JavaScript: List Channel Videos
Most 'list YouTube channel videos' tutorials use jQuery + the search.list endpoint — that costs 100 quota units per call (vs 1 for the uploads-playlist trick) and exposes your API key in the browser. This guide does it right: modern fetch + async/await, the playlistItems.list pattern, server-side API key proxying with Cloudflare Workers or Next.js Route Handlers, channel handle → ID resolution, pagination with nextPageToken, and the oEmbed fallback for simple embeds without any API key at all.
