“This is your last chance. After this, there is no turning back. You take the blue pill — the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill — you stay…


I am excited about this topic, since the technology we are going to talk about opens the way for a new generation of web-based apps, which can directly communicate across multiple browser windows without involving a backend.

However, there can be use cases where in…


The OffscreenCanvas Web API enables us to transfer the ownership of Canvas DOM elements into workers.

Since workers run inside a separate thread (using your own CPU if possible) this means that expensive app related JS logic can not slow down your Canvas rendering performance and vice versa: expensive logic…
