How to use CAML Query in Client Object Model

Most of us may face this issue in their application while using CAML in COM. That is,

var camlQuery = new SP.CamlQuery();

camlQuery.set_viewXml("<Query><Where><BeginsWith><FieldRef Name='Name'/><Value Type='Text'>asdf</Value></BeginsWith></Where></Query>");

                this.listItemCollection = oList.getItems(camlQuery);

                context.load(listItemCollection);

The above mentioned code may not give you the result. Replace CAML query like this,

var camlQuery = new SP.CamlQuery();

camlQuery.set_viewXml("<query><Query><Where><BeginsWith><FieldRef Name='Name'/><Value Type='Text'>asdf</Value></BeginsWith></Where></Query></query>");

                this.listItemCollection = oList.getItems(camlQuery);

                context.load(listItemCollection);
