46. @sendilkumarn PARSE COMPILE OPTIMISE EXECUTE GC JavaScript execution DECODE COMPILE EXECUTE WebAssembly execution Optimised already
47. @sendilkumarn Streaming compilation
48. What languages can do wasm? @sendilkumarn
49. C/C++ @sendilkumarn
50. @sendilkumarn ./emcc -O3 helloworld.c
51. Why C/C++? @sendilkumarn Tons of options All batteries included Verbose
52. Rust @sendilkumarn
53. @sendilkumarn $ wasm-pack build $ cargo install wasm-pack
54. Why Rust? @sendilkumarn Inbuilt into the compiler All batteries included Best tooling support Sometimes bigger binaries
55. AssemblyScript @sendilkumarn
56. @sendilkumarn $ asc helloworld.ts -b helloworld.wasm -O3 $ npm i --save-dev assemblyscript
57. Why AssemblyScript? @sendilkumarn Closer to JavaScript community Good tooling support / options
58. Go @sendilkumarn
59. @sendilkumarn $ GOOS=js GOARCH=wasm go build -o out/main.wasm go/main.go
60. Why Go? @sendilkumarn Easy & Concise TinyGo is awesome Reflections & Proxies everywhere
61. @sendilkumarn Future
62. @sendilkumarn Interface types
63. @sendilkumarn Single Instruction Multiple Data
64. @sendilkumarn ♻ Garbage Collection
65. @sendilkumarn WASI WebAssembly System Interface
66. JavaScript with WebAssembly together makes web even more awesome & faster @sendilkumarn
