> Julia uses a method JIT, which are quick to implement, but which makes latency gets bad. Meaning if you load a whole new package, running the first function can cause some delay. With a JavaScript style tracer JIT added into the mix one could have probably managed to have both high performance and low latency.
This is actually the other way around -- Method JITs are harder to implement and all the major JavaScript JITs are method JITs, not tracing JITs. There are many reasons that contribute to the latency but I don't see what makes method JITs inherently slower than tracing JITs.

The doc is incorrect, `let`(and even `var`) does perform as well as `const` in optimized code (but it comes with performance cliffs, if there is a re-assignment).

Native promises and bluebird use different microtask queues on Node which makes interop incorrect (which is also one of the reasons why bluebird is ES6 spec non compliant). See https://gist.github.com/anonymous/9936c695f2c29e79a0c1a0dec8...
This might lead to subtle ordering bugs, I would recommend against using both together.
Using bluebird and native promises together may result in slower performance because V8 has fast paths for native promises which fail for bluebird.
