CLASS_CONFUSION JS confusion full source code_js object-oriented

Use random strings to replace variables, etc. to obfuscate the original code and protect the code you wrote, which is not conducive to others directly plagiarizing

copying the code code As follows: /**//**//** ** ======================================== ======================== ======================== ============= ** Class name: CLASS_CONFUSION ** Function: JS obfuscation ** Example: ---------- --------------------------------------------- ------------------------------------------
