Iterable : Object

An iterable object is any object that returns a function that produces

an %%/Iterator|Iterator%% for its %%/Symbol#iterator|**Symbol.iterator**%%

property.

You can loop over all values in an iterable object by using a

**for (var value of iterable) { }** loop.

See %%/Iterator|Iterator%% for more details.

<example>

// Arrays are a built in Iterable object

var arr = ['a', 'b', 'c'];

// Use for (... of ...) loop to get the values of an iterable

for (var x of arr) {

console.log(x);

}

// Under the covers, for (... of ...) does the following:

var iterator = arr[Symbol.iterator]();

var current = iterator.next();

while (!current.done) {

console.log(current.value);

current = iterator.next();

}

</example>
