Repeat Text

This lesson is part of Web Developer Tools · All levels

Summary

Repeat text doubles a text by the number of times it is specified, with the option of separating between repetitions. This feature is useful for creating separator lines, placeholders, patterns, or test data. The results can be very large if the number of repetitions is high, so it needs to be limited. The separator is only placed between copies, not after the last copy.

Key points

Repetition means copying the text N times.
The separator is placed between copies, not at the end
JavaScript provides String.repeat(n)
Negative or non-negative integers need to be addressed
Limit the amount so the output doesn't consume memory
