Now, I'm not saying that “determining the object bound to this” makes for the lightest possible reading, but there is some small comfort to be found here: now that we understand when that determination is made, we’re well equipped to understand the what—and that fortunately, that breaks down to only a handful of distinct use cases, all of which share one big caveat in the form of arrow functions.Global Binding (formerly "default binding")Any code outside of a defined function lives in the global

WCAG is evolving. Since 1999, the Web Content Accessibility Guidelines have defined accessibility in binary terms: either a success criterion is met or not. But real user experience is rarely that simple. WCAG 3.0 rethinks the model — prioritizing usability over compliance and shifting the focus toward the quality of access rather than the mere presence of features. Could this be the start of a new era in accessibility?
