06. Binary Streams & Container Layouts

Execute native browser-level Base64 byte conversions and stream promise aggregation inside modular, container-responsive cards.

// 1. Native Uint8Array Base64/Hex encoding (Zero polyfills)
const encoder = new TextEncoder();
const bytes = encoder.encode("Web Engine 2026 Core");

const base64String = bytes.toBase64(); // Standard ES2026
const hexDump = bytes.toHex();          // "57656220456e67696e65..."

// 2. Stream promise aggregation via Array.fromAsync
async function* generatePayloads() {
  yield Promise.resolve({ chunk: 1 });
  yield Promise.resolve({ chunk: 2 });
}
const allChunks = await Array.fromAsync(generatePayloads());

Architectural Features

• Uint8Array.prototype.toBase64(): Native browser-level Base64 conversion avoiding polyfills and UTF-16 binary corruption.
• Array.fromAsync(): Aggregates async iterators and Promise streams into an array in a single call.
• Container Queries: Modular layout changes driven by parent container widths rather than the viewport.
