"It is probably fair to say that JavaScript is the most important technology these days when it comes to software engineering."

Uhh ... no?

+1 "JS is the only API we currently have to use one of the most popular plateform we have" would be more accurate. And it's a terrible API. I can't wait for webassembly.

digi_owl2• 10 years ago

Could have sworn that webassembly is just a subset of JS.

k__• 10 years ago

Uhh ... yes.

It didn't say it's the best, which it probably isn't.

It's maybe fair to say it's the most important technology when it comes to web development. The software engineering world is much bigger than just web development, though.

paulddraper• 10 years ago

Gosh, how do you even judge that....

If JS is super important, does that make C++ (the most common implementation language for JS runtimes) super-duper important?

Willing to bet $100 that there are more projects developing with Git than JS.

Actually wait...I GOT IT: the most important technology these days when it comes to software engineering is the microprocessor.

Some very good examples and a good explanation of the reasoning behind the previous and the current optimizations of the JavaScript execution infrastructure.

For the context, from the "about" page of the author, he:

"joined Google to work on the V8 JavaScript Engine in the Munich office, where" he's "currently working as tech lead for the JavaScript execution optimization team."

I apologize if this is an uninformed question, but are there any popular browser benchmarks out there? I'm sure that JS benchmarks are useful to browser developers and those who want JS to be the next general application platform, but as a user, I'm currently sticking to Safari since things like battery life and scrolling performance on mainly document-oriented pages are still more important to me.

the author mentions speedometer. It tests everything a browser needs to load and use a web app - styling, DOM parsing, JS...

All of these changes that the author is making are changes that the compiler should be generating.

Unless you work in the embeded systems I don't expect people to have done or needed the % 2048 trick.

sambe2• 10 years ago

The author is writing the compiler (and modifying it to make these changes). What do you mean exactly?

gravypod2• 10 years ago

I'm just wowed by this not already being part of V8. What else have they been doing?

I know that V8 has some amazing performance characteristics and if they aren't from doing things that C compilers have been doing for years, then what are these speed boosts coming from?

Is there a benchmark which tests boring real world usage? The web is littered with people complaining about the performance of dynamically adding rows to tables, especially in IE.

The good news is that the next version of Edge 15 has some really good DOM performance improvements.

chrisseaton• 10 years ago

But that's not the JS implementation - that's the DOM and layout implementation. Faster JS won't improve that.

The part about optimizing for the Mandreel-test by skipping some initialization has gone full circle, as this is now exploited by developers. https://github.com/nolanlawson/optimize-js
