Modern Syntax (JWP 8.0+):

const player = jwplayer('myElement').setup(
    playlist: 'https://cdn.jwplayer.com/manifests/MEDIA_ID.m3u8',
    // The property is simply 'license'
    license: 'YOUR_LICENSE_KEY_HERE'
);

Legacy Syntax (JW Player 7 & older): In older versions, the key was often passed as a query parameter in the library URL or as key in the setup config.

jwplayer.key = "YOUR_LICENSE_KEY_HERE";

JW Player operates on a Software-as-a-Service (SaaS) model. Unlike older versions that used simple text keys, the modern implementation relies on a unique Player ID and a License Token associated with your account.
