Data = {'Test1':2,'Test2':3,'Test3':4,'Test4':0,'Test5':4,'Test6':0};

In above line how to add the data and how to retrieve this data?Is any documentation is there to study?

My code:

 Data = {'Test1':2,'Test2':3,'Test3':4,'Test4':0,'Test5':4,'Test6':0}; 

console.log('::::::Data :::::;'+Data );

for(var name in Data ){

console.log('::::::name:::::;'+name);

createSlider(name,Data [name]);

}
