One Node source
import and require both load queue.js. The duplicate CJS build is gone.

- Migration
Version 3.0 → 3.1
Faster core. Same flow.
FIFO execution, explicit this.next(), CommonJS syntax, classic scripts, and the stack path remain available.
What changed
Two internals. One floor.
Task logic stays the same. Upgrade Node, then install.
Private fields
Instance state no longer pays for external WeakMap lookups.
Node 22.13 or newer
This floor supports warning-free synchronous CommonJS loading of the shared ES module.
easy-stack 2.1
The LIFO entry uses the same private-field and shared-module design.
No queue API rewrite.
Keep your imports, requires, task functions, and this.next() hand-offs.
Upgrade checklist
Verify the edges, then run.
- Move production and CI to Node 22.13 or newer.
- Keep ESM imports or CommonJS requires unchanged.
- Keep classic browser pages on
queue-vanilla.js. - Run the application integration suite.
- Compare your workload with
npm run benchmark.
