: Hiding strings in large arrays and accessing them via complex functions. Control Flow Flattening
Deobfuscating JavaScript often involves a multi-stage process of formatting, unpacking, and decoding to reveal the original logic. While no tool can perfectly restore original variable names, modern toolsets allow you to transform cryptic "jumble" into readable code for security analysis or debugging.

Ground truth was obtained via manual deobfuscation or original source (when available).
In reverse engineering, malware analysis, and web security, analyzing obscured scripts is a critical daily task. Developers often use minification and formatting shifts to protect intellectual property or reduce payload sizes. However, malicious actors regularly exploit these same techniques to hide malicious payloads from security scanners. Deobfuscating / Unminifying Obfuscated Web App / JavaScript
Sophisticated malware contains anti-deobfuscation defenses. Some scripts check if the code has been pretty-printed by counting whitespaces or measuring execution timing. If changes are detected, the script alters its execution path or crashes purposefully to deceive the analyst. Use tools that account for these checks by maintaining underlying code logic integrity.
