@sendilkumarn Hoi Nederland !!!
@sendilkumarn Languages are built for a purpose. Choose & Use
them wisely…
The state of WebAssembly Sendil Kumar N
@sendilkumarn Sendil Kumar
@sendilkumarn Hacking on WebAssembly
JavaScript is weird @sendilkumarn
[1, 2] + [3, 4] @sendilkumarn
1, 23, 4 @sendilkumarn [1, 2] + [3, 4]
1, 23, 4 @sendilkumarn [1, 2].toString() + [3, 4].toString() “1,2”
+ “3, 4”
JavaScript is weird* * - sometimes @sendilkumarn
@sendilkumarn JavaScript Execution
@sendilkumarn Load JavaScript
@sendilkumarn a.js AST 1001010010101101010 Execute Profiler Parse Interpret Compile 100101001010
Optimise 1010 GC
@sendilkumarn JavaScript Tuning
@sendilkumarn Css Tuning
JavaScript is awesome @sendilkumarn ~80% ~90% https://2019.stateofjs.com/opinions/
@sendilkumarn JavaScript is easy https://octoverse.github.com/ 6 years in row
@sendilkumarn https://2019.stateofjs.com/opinions/ ~59% ~40% JavaScript is evolving
So what is the problem? @sendilkumarn
@sendilkumarn Types Polymorphism Unpredictable Performance Runtime exceptions
@sendilkumarn Types 66% users interested to use TypeScript https://2019.stateofjs.com/javascript-flavors/
@sendilkumarn Predicatble Performance Types Unpredictable Performance Typed
WebAssembly @sendilkumarn
Yet Another Frontend framework?
@sendilkumarn 00 61 73 6D 01 00 00 00 Native
Code Binary JavaScript Javascript Engine Runtime
@sendilkumarn 00 61 73 6D 01 00 00 00 Native
Code Binary JavaScript Javascript Engine
WebAssembly is not a language @sendilkumarn
@sendilkumarn func add is called Stack get_local $lhs LHS RHS
get_local $rhs i32.add SUM Structured stack machine
@sendilkumarn 00 61 73 6D 01 00 00 00 Size
& Load time efficient
@sendilkumarn What WebAssembly provides?
@sendilkumarn Speed
@sendilkumarn Near Native perf. ~30% faster than JS
@sendilkumarn secure
@sendilkumarn Linear Memory Model
@sendilkumarn Shared Array Buffer
@sendilkumarn Typed

@sendilkumarn Boundary Crossing
@sendilkumarn Not always faster
@sendilkumarn How WASM works?
@sendilkumarn WebAssembly Execution
@sendilkumarn Load WebAssembly
@sendilkumarn Decode Compile Execute 00 61 73 6D 00 61

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