Any reason not to make it a class Timeout?

classTimeout{constructor(after){this._called=false;this._idleTimeout=after;this._idlePrev=this;this._idleNext=this;this._idleStart=null;this._onTimeout=null;this._repeat=null;}unref(){if(this._handle){this._handle.unref();}elseif(typeofthis._onTimeout==='function'){varnow=TimerWrap.now();if(!this._idleStart)this._idleStart=now;vardelay=this._idleStart+this._idleTimeout-now;if(delay<0)delay=0;// Prevent running cb again when unref() is called during the same cbif(this._called&&!this._repeat){exports.unenroll(this);return;}varhandle=reuse(this);this._handle=handle||newTimerWrap();this._handle.owner=this;this._handle[kOnTimeout]=functionunrefdHandle(){this.owner._onTimeout();if(!this.owner._repeat)this.owner.close();};this._handle.start(delay,0);this._handle.domain=this.domain;this._handle.unref();}returnthis;}ref(){if(this._handle)this._handle.ref();returnthis;}close(){this._onTimeout=null;if(this._handle){this._handle[kOnTimeout]=null;this._handle.close();}else{exports.unenroll(this);}returnthis;}}

No gain, more code change.

Well, it modernizes things a little and makes them more explicit. If we want to minimize change why not keep it const Timeout and do const Timeout = function Timeout - by naming the function expression you get the same trace.

Why even assign it though? It's unnecessary.

Typically we have avoided modernization unless it meant performance increases or was part of some refactor that touched the code a lot anyways.

Fair enough - I'm sorry if all these questions annoy you :)

this._called = false;
this._idleTimeout = after;
this._idlePrev = this;
