I didn't make C, Crystal, NodeJS and Golang benchmarks (and much more I didn't post) just for fun : I'm finishing Nectar, a native cross-platform compiler for javascript/ECMAscript.

Why a javascript native compiler ?

Javascript is everywhere : browser, server, IoT. NodeJS is fast, and slow. Fast, because it's a way faster than Python or Ruby, orhers interpreted languages. Slow, because compared to C, Crystal or Go, it's slow. There are a lot of advantages to truely compile javascript :

Speed (development && execution)

Size

Efficiency

Ecology

No need for Obfuscation

Web Assembly (wasm)

Fast coding and Fast execution

IoT

And much more ...

What is supported ?

A lot of ECMAscript 5 is currently supported : functions, variables, objects, arrays, standards functions/properties (typeof, .length, .toString()). I'm making a solid basis for the compiler be fast and secure.

For example, this is currently supported :

var a = 10; console.log(a); // print '10' a = "a string"; console.log(a); // print 'a string' a = 10.01231; console.log(a); // print '10.01231' var human = { fname: "John", name: "Doe", age: 10, type: "human"}; var robot = { name: "Bot", type:"robot", battery:90}; console.log(human.fname) // print 'John' var nestedArray = [0,"b",2,"d",["e","f",7],["i"]]; console.log(nestedArray[0]); // print '0' console.log(nestedArray[4][1]) // print 'f' callit(human); // print 'Hey Doe' callit(robot); // print 'Hey Bot' // definition of the function after the call function callit(obj) { console.log("Hey " + obj.name); }

Which platforms does Nectar support ?

Nectar currently support all platforms. It has been tested on Windows, Mac, Linux, x86, x64 and ARM. Executables size is low (for the example above < 10 ko). And Nectar is fast, really, really fast. Benchmarks are coming soon.

Cross-compilation

The better part is the cross compilation : it's possible to compile JS with Nectar from a supported platform to any other supported platform. We successfully compiled a "helloworld.js" from a Raspberry pi3 to a Windows 7 x86, a Windows 10 x64, and a Linux x64.
