if there is any problem with freecodecamp today, please tell me.

Hello there,

There is nothing wrong with freeCodeCamp, as far as I am aware.

Keep in mind, the tests are run on your browser. So, if tests are unexpectedly failing, it is likely an issue with your browser (provided your code is correct).

I suggest you try another browser, or ensure you do not have any sort of browser extention enabled with access to freecodecamp.org

Hope this clarifies
