The cost of JavaScript in 2019

The cost of JavaScript in 2019

Update to


Thought I’d stick this here:

For my taste the article (from April 25, 2018) lacks awareness of the continued evolution of browser-based resources as specified by the W3C like Web Workers (which more recently lead to Worklets which in turn inspired Task Worklets) and ServiceWorkers.

In parts it celebrates the “JavaScript-first” design approach while viewing “DOM-first” as past its prime.

In my opinion the “just JavaScript” perspective is misguided and it is a mistake to ignore JavaScript as the primary means to automate native browser resources (… which includes among other things interacting with browser-parsed, rather than JavaScript-created DOM nodes).
