I need to store some statistics using JavaScript in a way like I'd do it in C#:(我需要使用JavaScript来存储一些统计信息，就像在C＃中那样：)
Dictionary<string, int> statistics;
statistics["Foo"] = 10;
statistics["Goo"] = statistics["Goo"] + 1;
statistics.Add("Zoo", 1);
Is there an Hashtable or something like Dictionary<TKey, TValue> in JavaScript?(JavaScript中是否有Hashtable或类似Dictionary<TKey, TValue>类的东西？) 
Use JavaScript objects as associative arrays .(使用JavaScript对象作为关联数组 。)
Associative Array: In simple words associative arrays use Strings instead of Integer numbers as index.(关联数组：简单来说，关联数组使用String而不是Integer数字作为索引。) Create an object with(创建一个对象)var dictionary = {};
Javascript allows you to add properties to objects by using the following syntax:(Javascript允许您使用以下语法向对象添加属性：)
Object.yourProperty = value;
An alternate syntax for the same is:(相同的替代语法是：)
Object["yourProperty"] = value;
If you can also create key to value object maps with the following syntax(如果您还可以使用以下语法创建键值对象映射)
var point = { x:3, y:2 };
point["x"] // returns 3
point.y // returns 2
You can iterate through an associative array using the for..in loop construct as follows(您可以使用for..in循环构造遍历关联数组，如下所示)
for(var key in Object.keys(dict)){
var value = dict[key];
/* use key/value for intended purpose */
}
