Programming Style–Kendo & jQuery

• Which of the following do you prefer?
• Which is easier to read?
• Which is easier to write?
• Which is easier to maintain?

 var dataItem = this.target().closest(".k-grid").data("kendoGrid").dataSource.getByUid(this.target().closest("tr").data("uid"));

Or…

var dataItem = this.target()
                .closest(".k-grid")
                .data("kendoGrid")
                .dataSource
                .getByUid(this.target().closest("tr").data("uid"));

Or…

 var grid = this.target().closest(".k-grid").data("kendoGrid");
 var dataSrc = grid.dataSource;
 var dataItem = dataSrc.getByUid(this.target().closest("tr").data("uid"));

I’m not convinced the answers are obvious.
