Crossword clue: If-then-___, in coding

The term "if-then-else" is a common structure in programming and coding. In this structure, "if" checks a condition, "then" specifies what happens if the condition is true, and "else" provides an alternative action if the condition is false. This makes "else" the perfect answer to the crossword clue, as it completes the phrase and is essential for decision-making in code.
