The following code works:

 let check = checkingImages.every((item)=>item.classList.contains('matched'))

But this one doesn't:

let check = checkingImages.every((item)=>{
item.classList.contains('matched')
})

Can someone explain what's the reason for the second code not working, please?

If you put `{ }` around the body of a `=>` function, you need an explicit `return` statement. – Pointy Aug 10 '21 at 16:23
Thanks, it works! But why does it work without writing `return` in forEach() method – Ali Sherifov Aug 10 '21 at 16:27

Because `.forEach()` completely ignores values returned from callback functions. – Pointy Aug 10 '21 at 16:28
