JavaScript Clipboard_api Guide
The Clipboard API provides async read/write access to the system clipboard. Safer and more capable than document.execCommand. The guide walks through Clipboard Read/Write. Write text: `navigator.clipboard.writeText("text")`. Read text: `const text = await navigator.clipboard.readText()`. Write multiple: `navigator.clipboard.write([new ClipboardItem({"text/plain":blob,"text/html":htmlBlob})])`. Requires user gesture + HTTPS. Permission: clipboard-write, clipboard-read. `execCommand("copy")` fallback for older browsers. The guide is organized into 1 sections that build on each other, each pairing a prose explanation with runnable code. Related guides: Arrays, Strings, Numbers, Math, Date.
