@yourtwitter Network performance Description or Image @twitterhandle
@yourtwitter Shipping less JavaScript
@yourtwitter @mgechev • Minification/dead code elimination • Differential loading •
Code-splitting Shipping fewer bytes
@yourtwitter @mgechev • Minification/dead code elimination • Differential loading •
Code-splitting Shipping fewer bytes
@yourtwitter @mgechev Differential loading • Produce ES5 bundles for newer
browsers • Do not send polyfills to modern browsers • Smaller payload • Do not downlevel modern features • Faster execution • Smaller payload
@mgechev -65KB polyfills ~2-10% smaller bundles
@mgechev Step 1: Load HTML Step 2: Look at script
tags Step 2: Download right version Differential loading
@yourtwitter Differential loading <!DOCTYPE html> <html lang="en"> <head> <title>Differential loading
