node-immutable-tuple binary package in Ubuntu Focal arm64

 This library provides immutable finite list objects with constant-time
 equality testing (===) and no memory leaks.
 .
 This package exports a single function called tuple both as a default export
 and as an equivalent named export, so all of the following import styles will
 work.
 .
 Node.js is an event-based server-side JavaScript engine.
