How to prevent script execution before fonts are loaded?

Question

css

There is a script that works with fonts on the site.
When the page is first loaded, they are executed even before the font is fully loaded via @font-face and there are many jambs.
You need to run the script only after downloading the font files. How?

Answer 1

document.fonts.load("bold 16px Lato", "b").then(function() {
    //
});
