	constructor() {
		// Some Code
	}

	_getIPData() {

	}

	_setIPData() {
		// Some Code
	}

	_loadMap() {

}

const app = new App();

• How to use LealletsJs

const map = L.map('mapID').setView([lat, lon], 15);

// Google Map
L.tileLayer('http://{s}.google.com/vt/lyrs=m&x={x}&y={y}&z={z}', {
	maxZoom: 20,
	subdomains: ['mt0', 'mt1', 'mt2', 'mt3'],
}).addTo(map);

L.marker([lat, lon], {
	icon: L.icon({
		iconUrl: 'images/icon-location.svg',
		iconAnchor: [24, 56],
	}),
})
	.addTo(map)
