The below code works to get the current zoom level in ArcGIS 3.18 JavaScript API.

html, body, #map {
height: 100%;
width: 100%;
margin: 0;
padding: 0;

body {
background-color: #FFF;
overflow: hidden;
font-family: "Trebuchet MS";
}
</style>
<script src="http://js.arcgis.com/3.18/"></script>
<script>
var map;
require(["esri/map", "dojo/domReady!"], function(Map) {
map = new Map("map", {
basemap: "topo", //For full list of pre-defined basemaps, navigate to http://arcg.is/1JVo6Wd
center: [-122.45, 37.75], // longitude, latitude
zoom: 13
});
map.on("extent-change",function(evt)
{
console.log("extent change",map.getZoom());
if(map.getZoom() > 13)
map.setZoom(13);
}
);
});
</script>
But map.getZoom() or map.setZoom() is not a method in the ArcGIS 4.0 JavaScript API MAP Class.
How do I get the current zoom level in ArcGIS 4.0 map JavaScript?
