oh btw i forgot to say
Google has added a new security setting for V8 in Chrome 122, allowing users to disable V8 optimizers for enhanced protection
chrome://settings/content/v8
V8’s main job is to convert JavaScript code into efficient machine code that can be run directly by a computer’s processor. This process is called “JIT (Just-in-time) compilation” and it allows JavaScript code to execute much faster than if it were interpreted by the browser.
