In the final segment of the Hello World, we will explore how to create C++ components that can be called from JavaScript. We will look at Trixul’s Simple Interface Language (SIL), which is used to describe, in a language-neutral manner, the objects within a component. Trixul can convert a SIL file into C++ stub code, all you need to do is provide an implementation, compile the result into a shared library, and drop it into a components directory to make it available to JavaScript code.
