+
+## Sintaxe
+
+```js
+myMap[Symbol.iterator]
+```
+
+### Valor retornado
+
+A função iterativa do map, que é a {{jsxref("Map.prototype.entries()", "entries()")}}  por padrão 
+
+## Exemplos
+
+### Usando o \[@@iterator]\()
+
+```js
+const myMap = new Map()
+myMap.set('0', 'foo')
+myMap.set(1, 'bar')
+myMap.set({}, 'baz')
+
+const mapIter = myMap[Symbol.iterator]()
+
+console.log(mapIter.next().value) // ["0", "foo"]
+console.log(mapIter.next().value) // [1, "bar"]
+console.log(mapIter.next().value) // [Object, "baz"]
+```
+
+### Usando o \[@@iterator]\() com for..of
+
+```js
+const myMap = new Map()
+myMap.set('0', 'foo')
+myMap.set(1, 'bar')
+myMap.set({}, 'baz')
+
+for (const entry of myMap) {
+  console.log(entry)
+}
+// ["0", "foo"]
+// [1, "bar"]
+// [{}, "baz"]
+
+for (const [key, value] of myMap) {
+  console.log(`${key}: ${value}`)
+}
+// 0: foo
+// 1: bar
+// [Object]: baz
