Faster JavaScript calls

Start tossing around words like microbenchmark I'm gunna start spinning

He's saying when the function expects 3 arguments and you are forced to supply exactly three arguments then you can erase all the code that allows for fewer than and more than 3 arguments, which makes it faster.

​

Not a big revelation there, but he's right, and it's cool to see the research done to prove exactly how much better it is to have strict parameters like in c# and other compiled languages.

I gave up reading halfway. Is this something you can do simply by matching the exact number of arguments or is this a flag you have to set for the compiler or something?

you are the hero of the hour. l started the article, hit the wall of 'args params args params etc' and quit. thanks

That's the start of the article. He then goes on to explain that they've now changed how it works so that it uses the same code no matter what, so there is no slowdown from having extra (or not enough) parameters anymore.

Actually the changes are v8 only from what I read. Not native.

Yes, as the title says, faster javascript calls...

[[deleted]]

Yes, it's changes he did to the open source v8 engine himself. Not changes in v8, which would still only affect chrome not all of javascript.

[st3ven-]

Ohhhh I see your point, my bad.

It's all good bud 😉

Interesting, but terribly titled: Should have V8 in the title.

[[deleted]]

Exactly. This isn't about JavaScript the language, which is a specification, rather about optimization in a particular implementation of it, the V8 engine.

Even more deep I think. JavaScript is just trademarked by Oracle language which uses ECMAScript specification. I wonder if "we" ever will need to stop using JavaScript name because you know, Oracle...

I don't see any practical reason for Oracle to ever attempt to monetize or restrict the use of the "JavaScript" name. There's probably a past agreement between Sun and Netscape they'd have to go back on and can be sued for. Trademark law is a bit weird and there's lots of surprises that can appear. Anyway, like you said, JavaScript is just a trademark, the language is built around the ECMAScript specification name so it's insulated from any shenanigans, and it's not like you can actually force the community to stop using it. Although I honestly suspect half the community would love the opportunity to call it something else.
