Core Idea

When dealing with difficult JavaScript, don't immediately try to understand everything manually.

The methodology is:

Format the code → Identify obfuscation → Deobfuscate/unpack → Analyze functionality → Reverse engineer if necessary

1. Identify What You're Looking At

Before doing anything, determine whether the code is:

• Minified — formatting/whitespace has been removed.
• Obfuscated — the code has intentionally been transformed to make its logic difficult to understand.
• Encoded — data has been transformed into another representation.
• Packed — code and symbols have been compressed into a loader that reconstructs the original code at runtime.

Important distinction

Minification ≠ Obfuscation

Minification mainly makes code smaller.

Obfuscation intentionally makes code harder to understand.

Therefore:

Beautifying fixes formatting, but it does not necessarily remove obfuscation.

2. Beautify First
