Safari is the only browser to support TCO in JavaScript, which is an ES6 standard. It might be 6 years old, but TCO is a pretty freaking "cutting edge" functional-programming feature that adds a great deal of power to JavaScript.
Google initially added it, then removed it from Chrome claiming TCO makes it "difficult to debug". And that was that.
Now, regardless of the effect of TCO on debugging, Apple continued (and still continues) to support the standard long after Google opted-out. If it needed removing, it would have been much more tasteful if Google did it via the TC39 rather than on their own volition.
So in this case Google's "fast development cycle" helped them pull a useful feature far quicker than Apple's Safari team has. Google's behaviour in this smacks far more of IE6-era Microsoft than it does Apple.
