applying map.fitbounds()

I’m making a map using openstreetmap I want to show the location of UK when the map loads at very first I’m giving a lat and lng to show the location right now but I want to use map.fitbounds() function to exactly fit the Uk location on map;

const myMap = L.map('map').setView([52.3555, 1.1743], 6);
//getting map tile from open source free openstreetmap tile provider
const tileUrl = 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png';
//setting attribution at bottom
const attribution =
        '&copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> ';
        //adding attribution layer to map
const tileLayer = L.tileLayer(tileUrl, { attribution });
tileLayer.addTo(myMap);

Please right a code to fit Uk location in map using fitbounds
