FCC JavaScript not running correctly today? (For loops) - (SOLVED)

Tell us what’s happening:
Hello,

I’m having a weird issue where code I put int JavaScript into the window is not running correctly - specifically, for loops no longer seem to work for me. It seems that for loops only iterate once, and then continue with the rest of the code. Even something as simple as :

for (let i = 0; i < 10; i++) {
alert(i);
}

only displays “0”. I’ve copied and pasted solutions that I have saved into previous challenges as well, and all of a sudden, they don’t work anymore.

Has anyone else been experiencing this issue?
