Load Optimizely async
Raw
load-optimizely-async.js
/**
* Inline this into the <head> of your HTML document. Replace `PROJECT_ID` and optionally change timeout (now 1000ms).
*
* Based on https://help.optimizely.com/Set_Up_Optimizely/Synchronous_and_Asynchronous_snippet_loading
* Simplified for today's browsers (no `s.async` or `s.type` needed, no need to prefix with `window.`).
* Note: risk of using `document.appendChild`: https://www.paulirish.com/2011/surefire-dom-element-insertion/
