WebWorkerify of any JS funcion

WebWorkerify.js

Function.prototype.callAsWorker = function (context, args) {
	return new Promise((resolve, reject) => {
		const code = `
${context ? [...context].reduce((acc, cur) => acc + cur.toString() + '\n') : ''}

self.onmessage = async function (e) { 
	const result = await ( ${this.toString()}.call(null, e.data) );

	self.postMessage( result ); 
}`,
			blob = new Blob([code], { type: "text/javascript" }),
			worker = new Worker(window.URL.createObjectURL(blob));
		worker.onmessage = e => (resolve(e.data), worker.terminate(), window.URL.revokeObjectURL(blob));
		worker.onerror = e => (reject(e.message), worker.terminate(), window.URL.revokeObjectURL(blob));
		worker.postMessage(args);
	});
};

Usage:
function LocalLog(msg) {
// eslint-disable-next-line no-console
console.log(msg);
}
function someFunc(params){
const res = params.one + params.two;
LocalLog('worker res = ' + res);
}
const result = await someFunc.callAsWorker(
//context function passed in to worker
[LocalLog],
//parameters
{
one: 123, two: 467
}
);
LocalLog('Result returned from worker res = ' + res);
