Handlebar Helper Function: Repeat

Repeats a block of template code a specified number of times, providing loop context variables for each iteration.

This helper is available in the Winter ’26 release of Marketing Cloud Next (API version 65.0).

1{{#repeat count}}
2  Block content
3{{/repeat}}

The function repeats the block count times and returns the concatenated result.

Each iteration provides these loop variables:

• index: A 0-based index of the current iteration.
• first: A boolean indicating whether the current iteration is the first iteration.
• last: A boolean indicating whether the current iteration is the last iteration.
• All parent context variables.

If count is 0, the function returns an empty string. If the parameter is invalid, the function throws an exception.
