{isLoading || <Loader />}
<iframe

onLoad={onIframeLoad}
/>

I wrote the code like this at first.
this code is in react and with
const [isLoading, setIsLoading] = useState(true)
and In the onIframeLoad func With other works, i doing setIsLoading(false)
so i think loader component i cant see but i can see iframe with loader ???
so i changed the code {isLoading || } => {isLoading ? : ''} then it work well
but i dont understand what is difference code meaning
<Loader /> component will be visible when isLoading is false in your code.
{isLoading || <Loader />} should be {isLoading && <Loader />}.
<>
{isLoading && <Loader />}
<iframe
ref={iframeRef}
title="title"
src={src}
onLoad={onIframeLoad}
/>
</>
