At first, Emscripten sounds like the punch line to a tech joke: a compiler that converts C/C++ code into Asm.js, a subset of JavaScript that can then run via a Web browser or in the Node.js framework.

However, JavaScript compilers can optimize your JavaScript code and generate improved code. The compiled JavaScript files are smaller than your original JavaScript files, reducing download times ...

Using Microsoft Roslyn and Visual Studio, dev shops with C# assets can compile apps to run in the browser with no extra coding A new compiler lets programmers use their C# skills to build JavaScript ...

We looked last week at some of the things that can influence the speed of programming languages and how different approaches to running code can influence program performance. Some work described by ...
