Sample code

//PHP
<?php
error_reporting(E_ALL ^ E_NOTICE);
ini_set("display_errors", 1);

namespace my\Code;

use vendor\Something\SomeClass;

define("MY_CONST", 12345);

class MyClass
{
    function getSomething($param = [])
    {
        $my_array = [
            "keyA" => 123,
            "keyB" => "string",
        ];

        return $my_array;
    }
}

$objMyClass = new MyClass();

$execute = $objMyClass->getSomething();

//JS
var MyObj = {};

MyObj.customObject = {
    "id" : 123,
    "text" : null
};

MyObj.myFunction = function()
{
    var copy = JSON.clone(MyObj.x);

    copy.keyNum = 123;
    copy.keyStr = "hello";

    $("selector").text("test");

    var deferred = new $.Deferred();

    deferred.resolve();

    return deferred.promise();
}
