what efficient / elegant way iterate object values in javascript?

as example, assume following object: let myobj = {p1: "v1", p2: "v2"}

ecmascript 2017:

if target platform supports object.values:

object.values(myobj).foreach(value => /* */) 

if need property names well, can use object.entries in combination array destructuring:

object.entries(myobj).foreach(([key, value]) => /* */) 

ecmascript 5:

if need backwards compatible , don't want use polyfill:

object.keys(myobj).map(prop => myobj[prop]).foreach(value => /* */) 

older versions:

note for...in statement iterates on prototype's properties well, need filter them out using object.prototype.hasownproperty.

for (var key in myobj) {   if (myobj.hasownproperty(key)) {     var value = myobj[key];     //   } }
