How to read a column type SPUser, DateTime, Currency with EcmaScript?


Okay, I got a solution Sharepoint.Stackoverflow.com from user Vardhaman Deshpande. This works.
Here is How to get the value of each type of field:
Title  SP.ListItem.get_item(‘Title‘);

ID  SP.ListItem.get_id();

Url -SP.ListItem.get_item(‘urlfieldname‘).get_url()

Description  SP.ListItem.get_item(‘descriptionfieldname‘).get_description();

Current Version  SP.ListItem.get_item(“_UIVersionString“);

Lookup field  SP.ListItem.get_item(‘LookupFieldName’).get_lookupValue();

Choice Field  SP.ListItem.get_item(‘ChoiceFieldName‘);

Created Date  SP.ListItem.get_item(“Created“);

Modified Date  SP.ListItem.get_item(“Modified“); -> case sensitive does not work with modified

Created By  SP.ListItem.get_item(“Author“).get_lookupValue());

Modified by  SP.ListItem.get_item(“Editor“).get_lookupValue());

File   SP.ListItem.get_file();

File Versions -  File.get_versions();.

Content Type  SP.ListItem.get_contentType();

Parent List  SP.ListItem.get_parentList();
UPDATE: The following code is working and tested.
var item;
function getItemById(itemId){

    var clientContext = new SP.ClientContext.get_current();

    var web = clientContext.get_web();

    var list = web.get_lists().getByTitle('myList');

    item = list.getItemById(itemId);

    clientContext.load(item);

    clientContext.executeQueryAsync(onSuccess, onFailure);
}
function onSuccess(){

    alert(item.get_item("My User column").get_lookupValue());
}
function onFailure(){

    alert('Failure!');
}
