# Array Methods

While Enmap is a Map enhanced with Array methods, Enmap also offers some enhanced array methods for the data stored inside of it. Talk about Arrayception!

So what do I mean by methods for your stored data? I mean that you can store arrays inside Enmap, and directly push, pull, add and remove from those arrays. There are methods to work both on direct arrays, as well as arrays stored inside of an object.

Let's take a look at three example entries in Enmap that we can use. The first is a direct array, the second is an array inside an object, the last is an array of objects.

myEnmap.set("simpleArray", [1,2,3,4,5]);

myEnmap.set("arrInObj", {
  name: "Bob",
  aliases: ["Bobby", "Robert"]
});


myEnmap.set('objectarray', [{ a: 1, b: 2, c: 3 }, { d: 4, e: 5, f: 6 }]);

There are two methods to push to an array, one for simple arrays and one for arrays inside objects. Pushing in an Enmap array is the same as a regular array push: it adds the element to the end of the array.

myEnmap.push("simpleArray", 6);
// now [1,2,3,4,5,6]

myEnmap.push("arrInObj", "Robby", "aliases");
// now ["Bobby", "Robert", "Robby"]

The third parameter in push is the "path" to the array in an object. It works the same as the properties path used in Working With Objects.

Similarly, you can remove from an array. With the normal path system, you can either remove via the index in the array, or remove simple strings. To remove a complex object, you'll need to use a function in the remove method.

myEnmap.remove("simpleArray", 2);
// now [1,3,4,5,6]

myEnmap.remove("arrInObject", "Bobby", "aliases");
// now ["Robert", "Robby"]

myEnmap.remove('objectarray', (value) => value.e === 5);
// value is now [{ a: 1, b: 2, c: 3 }]
