📚 Tech Specs: The Power of string.repeat()

In modern JavaScript (ES6+), repeating a string is handled by the native string.repeat() method. Before 2015, developers relied on "hacks" like Array(n + 1).join(string), which were less readable and harder to optimize.

The native repeat() method is significantly faster because it’s optimized at the engine level (like V8 in Chrome). This tool leverages that native performance to deliver near-instant results, even when generating tens of thousands of repetitions.
