Developing with WebAssembly: pitfalls and examples

This talk is about pitfalls we fell into while moving our big app to C++ in browser.

We'll discuss:

• the instruments and what they can do;
• how to throw objects between JS and Wasm;
• the problems you can face and how to solve them;
• the things Wasm can and cannot do;
• how to find C++ code in browser debugger;
• how much faster than JS is Wasm.
