WebAssembly: Yes, but for What?

WebAssembly (Wasm) has found a niche but not yet filled its habitable space. What is it that makes for a successful deployment? WebAssembly turns 10 this year, but in the words of William Gibson, we are now as ever in the unevenly distributed future. Here, we look at early Wasm wins and losses, identify winning patterns, and extract commonalities between these patterns. From those, we predict the future, suggesting new areas where Wasm will find purchase in the next two to three years.
