repeat3

repeat3 is a fixed-count control structure used to execute a block of code three times in immediate succession. It represents a concise form of a loop when the exact number of iterations is known in advance and constant.

In languages that support it as a syntactic construct, repeat3 applies the enclosed block three times without requiring an explicit loop counter. Conceptually, it is equivalent to a for-loop or while-loop that runs three iterations. For example, a pseudocode expression such as repeat3 { block } is functionally the same as for i from 1 to 3 do block. Some language implementations treat repeat3 as a macro or built-in function that expands to the repeated execution of the block.

Examples and usage notes: a call like repeat3 { print("tick") } would perform the print operation three times. If a language does not provide native repeat3 syntax, the same effect can be achieved with a standard fixed-count loop, such as for i in 1..3 or while count < 3, incrementing a counter.

Variants of the concept include repeatN, which repeats a block N times, and general fixed-count forms that replace the constant 3 with a variable or parameter. While repeat3 can reduce boilerplate in simple scenarios, it is less common in modern mainstream languages, where explicit loop constructs offer greater flexibility and readability for more complex control flow.
