Note, when it says "1.6x faster" what is really means is "1.6 as fast" or "60% faster", or really "operates at 1.6x the speed of the baseline", not "1.6x increase in speed". For example, whe

I haven't written enough ES6 to answer this for myself, but doesn't the dynamic nature of the language mean that constants can be at risk of invalid LHS operations at run-time? (At least, those positioned high enough in the scope

I appreciate the information. I'm curious, in reference to the original quote, how much of the existing ES5 optimization story do you think can be leveraged (at least within V8) to bring ES6/7 on par with raw ES5 and how much nee

Regarding the scope optimizations: that's an interesting point. I wonder if the different scoping of let / const also create a performance penalty versus var .
155.
by venning 11y ago
That's still a check that var is not subject to. Hence, it's a little slower (in theory).

by venning 11y ago
I wouldn't be surprised if const and arrow functions actually make things slower. const , or at least a naive implementation of it, requires checking if the value is changed which var does not. Perhaps that could be equally perf

> ES6 performance sucks! Strong mode is a mode for ES6, you cannot use it without using various ES6 features. However, idiomatic ES6 code currently is substantially slower than ES5, across all browsers -- easily by 2x, often by 10x or m

Yes and no. The repetitions would have to appear within 32KB of each other to be captured in the DEFLATE window [1] which, given that a lot of pages can be 100s of KBs of uncompressed text, may make that impossible. Additionally, the zlib

I guess, but not really my point. All the projects that go through massive rewrites to port into another language always seem to attribute the gains they inevitably find to the new language and not to the fact that they completely restruct

You are not dumb. Releasing un-commented code that works is still releasing code that works. This actually solves a problem I was having. Thanks for sharing it.

I doubt that. This update is entirely client-side, while a rating system requires data management server-side in addition to the user interface elements. That doesn't mean ratings are difficult, just more difficult than this. Besides,

Thank you for teaching me "superstimulus". That word pretty much captures my concerns with linkbait and the like. https://en.wikipedia.org/wiki/Supernormal_stimulus

I think it is precisely that harshness that pushes the original title towards linkbait. Again, I'm not questioning the legitimacy of the involved developers' emotions. The point of a linkbait title is to elicit an emotional respo

This is one of those squishy things that's hard to assess. For me, I would stop short of a title that would be unacceptable if you substituted a (private) person's name for the company/country/whatever mentioned. If it

The HN Guidelines [1] state that submissions "should use the original title, unless it is misleading or linkbait." While I am sure the emotions of the developers affected by this are legitimate and strong, the original title bord
