- While custom JS is allowed in <a href="../documentation/components/reference/amp-script.md">
amp-script</a>, and third-party JS is allowed in iframes, it cannot block rendering. For example, if third-party JS uses the <a href="http://www.stevesouders.com/blog/2012/04/10/dont-docwrite-scripts/">super-bad-for-performancedocument.writeAPI</a>, it does not block rendering the main page.

- Third-party JS likes to use synchronous JS loading.
- They also like to
document.writemore sync scripts. - For example, if you have five ads on your page, and each of them cause three synchronous loads, each with a 1 second latency connection, you’re in 15 seconds of load time just for JS loading.
- AMP pages allow third-party JavaScript but only in sandboxed iframes.
- By restricting them to iframes, they can’t block the execution of the main page.
- Even if they trigger multiple style re-calculations, their tiny iframes have very little DOM.
