Text Repeater

The Text Repeater is a precision engineering utility designed for generating massive volumes of string data. While common tools fail at high iteration counts, this architecture utilizes memory-efficient string concatenation and buffer management. It addresses the critical need for stress-testing database character limits, populating UI mockups with variable-length filler, or creating complex text patterns for automated scripts. The system handles large-scale operations by decoupling the internal data buffer from the Document Object Model, preventing browser freezing during the generation of n-length strings. This ensures that even when generating millions of characters, the interface remains responsive and the data remains portable via text-file export.

The core logic utilizes an iterative accumulation pattern where the final string S_total is defined by the input string s, the separator d, and the iteration index i.

When Sequence Injection is enabled, the string is modified by the incrementing function:

To maintain O(n) complexity, the engine joins an array of pre-calculated segments rather than performing string-to-string additions, which avoids frequent re-allocation of memory buffers.
