Pika – Universal javascript is here

ES module syntax (ESM) is JavaScript’s latest native module system. Officially ratified in 2015, its import/export syntax is more compact, more easily analyzed and more reliably optimized. This all results in smaller, faster JavaScript on the web.

How does ESM make my website 90% faster?

ESM introduces something new to JavaScript and the way the web works: every JavaScript module can now be indexed and cached in a way that is universally accessible. That means that any site can push new changes and a user’s browser will only fetch the files that have changed. No more bundling dependencies with source code. No more single-line changes blowing out your application’s entire cached bundle.
