Obfuscated JavaScript

Imagine you are a cybersecurity analyst at a mid-sized tech company. One morning, you receive multiple reports from employees that their web applications are behaving erratically. Upon investigation, you discover that the source code of several critical JavaScript files has been heavily obfuscated, making it difficult to understand and troubleshoot the code. This obfuscation includes the insertion of numerous misleading comments, variable renaming, and string encoding. Your task is to analyze the obfuscated JavaScript code, identify the obfuscation techniques used, and determine if any malicious code has been inserted.
