FontFaceSet: forEach() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨January 2020⁩.

Note: This feature is available in Web Workers.

The forEach() method of the FontFaceSet interface executes a provided function for each value in the FontFaceSet object.

forEach(callbackFn)
forEach(callbackFn, thisArg)

Function to execute for each element, taking three arguments:

value, key: The current element being processed in the FontFaceSet. As there are no keys in a FontFaceSet, the value is passed for both arguments.
set: The FontFaceSet which forEach() was called on.

Value to use as this when executing callbackFn.

Undefined.
