WebAssembly Tutorial - 2 - Wrapping Functions with ccall and cwrap

In the second installment to this series, we look at basic function calls. We learn how to export functions from our C code to webassembly so they can be called in JavaScript. We look at how to use the two helper methods in JavaScript, ccall() and cwrap(). We examine the possible uses of these methods along with some of the drawbacks.

Hello there, I tried using your video to make my C++ function invoked with the use kf Webassembly. I sort of copied your procedure and I got an error saying Assertion Failed. What am I missing?
