It actually wasn’t, they didn’t use key with ng-repeat in benchmarks. Even Angular 1 was actually faster back then when used correctly: https://500tech.com/blo

  That post only invalidates* a specific measurement, but doesn't provide counter-measurements, especially not ones that say Angular.js was faster than React. Although I don't have alternative numbers, and will agree that VDOM comes with a performance penalty, Angular.js's method of change detection was pretty inefficient and required a lot of hand-holding. Still, I think either were sufficient for most use cases, and performance definitely isn't the main selling point for React (nor Angular.js). *Well, somewhat - it was still easier to shoot yourself in the foot, performance-wise, in Angular.js, but that's not really the point here, and React has its own issues there (e.g. `key`).
