Reactjs – What is causing the warning 'Removing intrinsics.%ArrayPrototype%.toReversed' in React?

I am getting this warning on first load of my App.
I’m using React.

lockdown-install.js:1 Removing intrinsics.%ArrayPrototype%.toReversed intrinsics.%ArrayPrototype%.@@unscopables.toSpliced intrinsics.%ArrayPrototype%.@@unscopables.toSorted

I really have no idea what this is about, so there’s nothing that I have previosuly tried.

I went into the node_modules to try and find something related to it… been searching on the internet and even chat GPT but the information that I found is vague.

    I randomly started getting this in my project right around the time you made this post which was odd.

    Do you have Metamask installed as a browser extension? I disabled the extension and the warnings went away.

    I found this post: https://github.com/MetaMask/eth-phishing-detect/issues/11900
    Which potentially suggests that something in our projects are triggering metamasks anti-phishing feature somehow? Not quite sure, but disabling the extension removed the warnings and confirmed it wasn’t something in my app directly.

    Disabliing MetaMask extension will solve this problem.
