however that fact that it is NOT using V8 is quite refreshing change. We need diversity in the JS eco system other than google v8. Didn't realize JavascriptCore is faster than v8.

To be fair they only said it starts faster than V8, nothing was said on runtime performance

This is the same weak argument that's being used to sell native compilation on Java. Tons of graphics showing startup time improvement, never a word on what happens after. But the only cases where this metric makes a real difference are CLI utilities and Serverless (if you know others, please tell me)

That’s not true, as far as I've read. I feel it is spelled out pretty thoroughly: Startup time and memory footprint are way lower, but peak performance is also lower: JIT outperforms static compilation due to it having more information. There are some tools to gather such information by running the program for a while, gathering stats, but JIT still outperforms.

Careful there. The JavaScript ecosystem is nothing if not diverse...
