Trying to add html basemap

Question

Hello, I am trying to add a URL (aerial image) as a basemap to my html code but I can not seem to figure it out.

I currently have it set up like this:

function init() {
 map = new esri.Map("map", {
 basemap: "streets",
 center: [-117.885170, 33.883592],
 zoom: 16
 });

If someone could help me out that would be great. Thanks.

Here is the help doc for basemaps class that has a code snippet for use a custom basemap: esri/basemaps | API Reference | ArcGIS API for JavaScript 3.18 require([ "esri/basemaps", "esri/map", "dojo/domReady!" ], function (esriBasemaps, Map){ esriBasemaps.delorme = { baseMapLayers: [{url: "https://services.arcgisonline.com/ArcGIS/rest/services/Specialty/DeLorme_World_Base_Map/MapServer"} ], thumbnailUrl: "https://www.example.com/images/thumbnail_2014-11-25_61051.png", title: "Delorme" }; var map = new Map("ui-map", { basemap: "delorme", center: [-111.879655861, 40.571338776], // long, lat zoom: 13, sliderStyle: "small" }); });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
