Zeptomatch is a tiny, fast, and dependency-free JavaScript library providing pattern matching similar to Zepto selectors. It allows you to efficiently determine if an element matches a specific selector string, offering a lightweight alternative to full-blown DOM manipulation libraries for focused matching tasks. Zeptomatch excels in scenarios requiring simple selector checks within a DOM structure, prioritizing speed and minimizing overhead. This makes it perfect for performance-sensitive applications or environments with limited resources.
