ES6 - Collections Set values() and keys()
The values method returns a new Iterator object that contains the values for each element in the Set object. The keys() function too behaves in the same fashion.
Syntax
mySet.values(); mySet.keys();
Return Value
A new Iterator object containing the values for each element in the given Set.
Example
var mySet = new Set(); mySet.add("Jim"); mySet.add("Jack"); mySet.add("Jane"); console.log("Printing keys()------------------"); var keyitr = mySet.keys(); console.log(keyitr.next().value); console.log(keyitr.next().value); console.log(keyitr.next().value); console.log("Printing values()------------------"); var valitr = mySet.values(); console.log(valitr.next().value); console.log(valitr.next().value); console.log(valitr.next().value);
Output
Printing keys()------------------ Jim Jack Jane Printing values()------------------ Jim Jack Jane
Example: Iterating a Set
'use strict' let set = new Set(); set.add('x'); set.add('y'); set.add('z'); for(let val of set){ console.log(val); }
The following output is displayed on successful execution of the above code.
x y z
