JS: Map.prototype.values

New in ES2015.

map_obj.values()

Return a iterator (also is a iterable) for the values in the map map_obj.

[see JS: Iterator]

const mm = new Map([[3, "n3"], [4, "n4"], [5, "n5"] ]);

for (let k of mm.values()) { console.log(k) }
// prints
// n3
// n4
// n5

for (let [k,v] of mm) { console.log(v) }
// prints
// n3
// n4
// n5

This example shows the result is iterator and iterable:

const mp = new Map( [[1,2], [3,4]]);

console.log ( mp.values ); // [Function: values]
// result is a function that returns a iterator object

// call it
console.log ( mp.values() ); // MapIterator { 1, 3 }
// result is a iterator object

// is also a iterable
console.log (
 Symbol.iterator in ( mp.values() )
); // true
