escape‑latex is a small Node.js library that safely escapes characters that have special meaning in LaTeX (e.g., # $ % & \ ^ _ { }) so that arbitrary JavaScript strings can be inserted into LaTeX documents without causing syntax errors. It offers options to preserve original formatting (converting spaces, tabs, and dashes to LaTeX‑compatible equivalents) and to customize the escape mapping, making it useful for developers who need to generate LaTeX output programmatically.
