Exhaustive Matching

type Shape = Circle | Square;

function getArea(shape: Shape) {
  switch (shape.kind) {
    case "circle":
      return Math.PI * shape.radius ** 2;
    case "square":
      return shape.sideLength ** 2;
    default:
      const _exhaustiveCheck: never = shape;
      return _exhaustiveCheck;
  }
}

Utilities.sleep(milliseconds);

Google Script Simple Trigger

On Open

Putting it at the top outside of the namespace in shared.ts is the convention in use

function onOpen() {
    const menu = SpreadsheetApp.getUi().createMenu('Scripts');
    menu.addItem('Displayed Text', 'functionName').addToUi();
    menu.addItem('Button 2', 'functionName2').addToUi();
}

On Edit

function onEditBody(e: GoogleAppsScript.Events.SheetsOnEdit) {
        if (
            (e.range.getColumn() !== OUTPUT_COL_DATE) &&
            (e.range.getColumn() !== OUTPUT_COL_TIME_START) &&
            (e.range.getColumn() !== OUTPUT_COL_TIME_END) &&
            (e.range.getWidth() === 1) &&
            (e.range.getHeight() === 1)) {
            // Do the needful (note variables on rhs above are not automatically defined)
        }
    }
