runAsyncadvanced

Runs a function in a separate thread by using a Web Worker, allowing long running functions to not block the UI.

Create a new Worker using a Blob object URL, the contents of which should be the stringified version of the supplied function. Immediately post the return value of calling the function back. Return a promise, listening for onmessage and onerror events and resolving the data posted back from the worker, or throwing an error.

const runAsync = fn => {
-  const blob = `var fn = ${fn.toString()}; postMessage(fn());`;
   const worker = new Worker(
-    URL.createObjectURL(new Blob([blob]), {
+    URL.createObjectURL(new Blob([`postMessage((${fn})());`]), {
       type: 'application/javascript; charset=utf-8'
     })
   );
