> I’ll be a little bit mad if this Preact/Angular inspired thing Signals predate both and originate in KnockoutJS at least. They were popularized in recent years by SolidJS. And then adopted into Preact, Vue and others. Angular is a very late newcomer to the signals game. Edit: and this is literally in the introduction section: --- start quote --- This first-class reactive value approach seems to have made its first popular appearance in open-source JavaScript web frameworks with Knockout in 2010. In the years since, many variations and implementations have been created. Within the last 3-4 years, the Signal primitive and related approaches have gained further traction, with nearly every modern JavaScript library or framework having something similar, under one name or another. --- end quote --- The list of libraries in the README is alphabetized, and doesn't reflect the evolution of signals in the frameworks and libraries.
