Build ArcGIS Mapping Apps with TypeScript

on YouTube ↗01h 45m

" summary

ArcGIS API for JavaScript v4 is now 100% TypeScript API and the demos show concrete results: a US-counties feature layer with optimized outFields and a legend/layer-list UI, and a time-slider-driven geojson playback of earthquakes that runs client-side visual variables, applies feature effects, and returns statistics (one day peaks show up to 128 quakes). Code and working samples live on GitHub, use widgets (legend, layer list, expand, time slider) and compile to plain JS that runs in the browser.
