    GopherJS

    GopherJS

    Compiler from Go to JavaScript for running Go code in a browser

    GopherJS compiles Go code to pure JavaScript code. Its main purpose is to give you the opportunity to write front-end code in Go which will still run in all browsers. Nearly everything is supported, including Goroutines (compatibility documentation). Performance is quite good in most cases, see HTML5 game engine benchmark. Cgo is not supported. GopherJS requires Go 1.16 or newer. If you need an older Go version, you can use an older Gopher release. GopherJS uses your platform's default GOOS value when generating code. Supported GOOS values are: linux, darwin. If you're on a different platform (e.g., Windows or FreeBSD), you'll need to set the GOOS environment variable to a supported value. gopherjs serve is a useful command you can use during development. It will start an HTTP server serving on ":8080" by default, then dynamically compile your Go packages with GopherJS and serve them.

    Chor

    A choreography programming language for concurrent systems

    Chor is a strongly-typed choreography programming language for distributed systems. In Chor, the behaviour of a system is written down as a global program (a choreography) where all the message exchanges between the participants are explicit. Choreographies are statically checked against protocol specifications, given as types, enabling type-directed global programming. Finally, Chor supports the automatic generation of systems from a choreography. With Chor, you do not have to worry about asynchronous communications or protocol compliance anymore. The language is based on strong theoretical bases, so that you can let its compiler do the jobs of checking your global programs and generating correct implementing code for you!
