anatomy of AMD module loading
require([
"esri/map", "esri/InfoTemplate", "esri/layers/FeatureLayer",
"dojo/parser", "dojo/domReady!"
], function( //Beginning of anonymous callback which fires when modules have been loaded.
Map, InfoTemplate, FeatureLayer,
parser //Variable names to refer to loaded modules
) {
parser.parse(); //first line of actual callback code
map = new Map("mapDiv", {
basemap: "national-geographic",

load comparison
//legacy
dojo.require(“esri.layers.FeatureLayer”);
var featureLayer = new esri.layers.FeatureLayer("url");
//AMD
require([
"esri/map", … "esri/layers/FeatureLayer"
], function(

dojo vs. dom
dojo.byId("messages").innerHTML = "howdy"; //legacy
//becomes
dom.byId("messages").innerHTML = "why, hello there"; //AMD

loop through response fields and find 'esriFieldTypeOID' instead of pulling information from response.objectIdFieldName (which is only present in a response from FeatureServer layer.
if(response.features.length && !response.error){
//loop through fields returned by service
for (var j = response.fields.length - 1; j >= 0, j--) {
//find field with type 'esriFieldTypeOID' and use its name as an attribute when converting to GeoJSON
if(response.fields[j].type == "esriFieldTypeOID")
var idKey = response.fields[j].name
}
for (var i = response.features.length - 1; i >= 0; i--) {
var feature = response.features[i];
var id = feature.attributes[idKey];

this is a gist to remind john and matt how to query for the maximum value in a field manually (since the JS api doesnt have any tools to limit query results)
use outStatistics

a few different examples of providing dojo AMD loader configuration options
//sometimes we see..
<script>var dojoConfig = { async: true };</script>
<script src="http://js.arcgis.com/3.10/"></script>
//or maybe..
<script data-dojo-config="async:true" src="http://js.arcgis.com/3.10/">
