A retry operation, a menu prompt, or paginated API processing are common examples. That is exactly where the TypeScript do-while loop helps. It runs the loop body first and checks … Read more >>
When I process sales records from an API or scan dashboard data for the first failed import, I rarely need to inspect every item.
