JavaScript String_repeat Guide
String.repeat() repeats a string count times. Useful for generating patterns, padding, and visual effects. The guide walks through String Repeat. `"*".repeat(10)` = "**********". `"ab".repeat(3)` = "ababab". `" ".repeat(level * 2)` — indentation. `"=".repeat(40)` — divider lines. Build visualizations: `"█".repeat(value / maxValue * 20)`. Zero repeat: `"x".repeat(0)` = "". Negative or infinity repeat throws RangeError. The guide is organized into 1 sections that build on each other, each pairing a prose explanation with runnable code. Related guides: Arrays, Strings, Numbers, Math, Date.
