isCellGridRange
function isCellGridRange(gridRange: GridRange): boolean;
One row and one column, measured by the bounds rather than by how the range was written: the end indices are exclusive, so a single cell is endRowIndex - startRowIndex === 1 and the same for the columns. A range with a bound left out is open in that direction and is never a single cell.
isX and nonX answer a question and never interrupt control flow; requireX and requireNonX hand the value back or throw. The scheme is explained in Validation conventions.
