Set.prototype.entries()
The entries()
method returns a new Iterator object
that contains an array of [value, value]
for each element
in the Set
object, in insertion order. For Set
objects there
is no key
like in Map
objects. However, to keep the API
similar to the Map
object, each entry has the same value for its
key and value here, so that an array [value, value]
is
returned.
Syntax
entries()
Return value
A new iterator object that contains an array of [value, value]
for each
element in the given Set
, in insertion order.
Examples
Using entries()
var mySet = new Set();
mySet.add('foobar');
mySet.add(1);
mySet.add('baz');
var setIter = mySet.entries();
console.log(setIter.next().value); // ["foobar", "foobar"]
console.log(setIter.next().value); // [1, 1]
console.log(setIter.next().value); // ["baz", "baz"]
