JavaScript obfuscation is a technique used to make web scraping more difficult by making the code harder to interpret.
Common obfuscation techniques include changing variable and function names, encoding data, control flow obfuscation, dead code insertion, minification, and function wrapping.
JavaScript deobfuscation is important in web scraping to extract hidden or dynamically loaded data, bypass anti-scraping measures, and interact with obfuscated JavaScript code.
Deobfuscation can be done through manual inspection, automated deobfuscators, debugging tools, and code beautifiers. Headless browsers can also help deal with obfuscated JavaScript.
