block-lambda would be nice

blamda.js

var OrderManager = {
      getRecordById: function (id) {

         function gridCheck (TypeOrder) {
            if (TypeOrder != null) {
               var record = TypeOrder.getGrid().store.getById(id)
               if (record) {
                  return { // would like the parent function to exit here (but ain't gonna happen)
                     record: record,
                     grid: TypeOrder.getGrid()
                  }
               }
            }
         }

         gridCheck(UnassignedOrder)
         gridCheck(SavedOrder)
      }
}

// Would be nice to say:
let OrderManager = {
      getRecordById: function (id) {

         let gridCheck = { |TypeOrder|
            if (TypeOrder != null) {
               let record = TypeOrder.getGrid().store.getById(id)
               if (record) {
                  return { // return worked!
                     record: record,
                     grid: unassigned.getGrid()
                  }
               }
            }
         }

         gridCheck(UnassignedOrder)
         gridCheck(SavedOrder)
      }
}
