Goal Determine whether a small Node.js or bundler-based application can migrate to core-js 3.x without downtime while importing core-js/stable, or whether core-js/pure is required to avoid changing native built-in behavior. Constraints and uncertainty core-js 3.x's core-js/stable entry point patches native globals such as Promise, Array, and String at import
