This module wraps typed arrays with a minimal abstraction so that you can resize and append to them without reallocating and transferring data yourself.
When initializing, you may pass an Array, a typed array, a size, or a dtype string. (Adding a dtype string will cast the data if necessary.) The following are equivalent ways to initialize a double precision dynamic typed array.
Minimal example making webpack and wasm/Emscripten work together.
Build instructions:
npm installnpm starthttp://localhost:8080
| npm config set loglevel http | |
| npm config set progress false | |
| npm config set package-lock false | |
| npm config set save false | |
| mkdir -p ~/.config/configstore/ | |
| printf '{"optOut": true,"lastUpdateCheck": 0}' > ~/.config/configstore/update-notifier-npm.json |
Together with HellMood we won this year's (2016) JS1K competition and thought this might be a good opportunity to write about the development process and my motivation behind it. If you're already familiar with JS1K, feel free to skip the next two paragraphs.
