JS++ is a proprietary programming language for web development that extends JavaScript with a sound type system. It includes imperative, object-oriented, functional, and generic programming features.
History
[edit]JS++ first appeared on October 8, 2011.[1][2][3] The modern implementation was announced at DeveloperWeek 2016[4] and released on May 31, 2016.[5][6][7][8] The language is designed by Roger Poon and Anton Rapetov.
Syntax
[edit]Type annotations
[edit]Since JS++ is a superset of JavaScript, declaring types for variables is optional.
int x = 1; // declares the variable x with an "internal type" (JS++ type)
var y = 2; // declares the variable y with an "external type" (JavaScript type)
bool z = true; // declares the variable z with an "internal type" (JS++ type)
Features
[edit]JS++ features a type system that is sound.[9][10]
JS++ is able to efficiently analyze out-of-bounds errors at compile time.[11][12][13]
Development tools
[edit]Compiler
[edit]The JS++ compiler is available for Windows, Mac OS X, and Linux. The compiler generates JavaScript output.
Editor integration
[edit]JS++ integrates with various code editors including Visual Studio Code, Atom, and Sublime Text.[14][15][16]
Build tools
[edit]JS++ can be integrated with third-party build tools like Webpack.[17]
