FontFace: family property

The FontFace.family property allows the author to get or set the font family of a FontFace object.

The value is used for name matching against a particular font face when styling elements using the font-family property. Any name may be used, and this overrides any name specified in the underlying font data.

This property is equivalent to the font-family descriptor of @font-face.

let fontFace = new FontFace(
  "Roboto",
  "url(https://fonts.example.com/roboto.woff2)",
);
console.log(fontFace.family); // 'Roboto'

fontFace.family = "newRoboto";
console.log(fontFace.family); // 'newRoboto'
