Why Does READ TABLE with BINARY SEARCH Miss a Row That Is There?
BINARY SEARCH trusts that the table is sorted ascending by the search key and discards half at each step. Using a fictional example, this note covers why an existing row is missed when the sort is absent or different, how to use sy-subrc 4 and 8 and sy-tabix on a miss, and the sorted secondary key alternative.
Why doesn't await inside forEach pause the loop?
forEach never keeps the Promise an async callback returns, so the next line runs before the saves finish and errors never reach try...catch. Using actual Node.js v24.21.0 output, this note shows when to use for...of, map with Promise.all, batches, or Promise.allSettled.

Called without a compare function, sort() converts numbers to strings and sorts them in dictionary order. Using actual Node.js v24.21.0 output, this note covers what a compare function must return, how sort() differs from toSorted(), and how to sort file names and multilingual strings with Intl.Collator.
Banks' loan-deposit spread in August: 1.19 or 2.20 points, which is right?
