ROSETTA PHASE 02

Modern Agenda: ECMAScript 2026

ROSETTA PHASE 02

Build the strongest framework-free implementation using current JavaScript and native browser capabilities. The visible target remains comparable with every other Modern Agenda phase.

Purpose & Learning Objectives

Why this project exists and what the implementation should teach.
Purpose / Learning

Purpose

Build the strongest framework-free implementation using current JavaScript and native browser capabilities.

Learning Objectives

  • Use current ECMAScript syntax without unnecessary transpilation.
  • Prefer browser-native APIs where they solve the problem well.
  • Use modern async/await and module organization.
  • Write accessible, semantic interaction without framework dependencies.
  • Establish a current JavaScript benchmark for framework comparisons.
