    connection.type:

    It identifies the network information state and connection type of the device.

    Example:

        var network_State = navigator.connection.type;
    
        var n_states = {};
        n_states[Connection.UNKNOWN]  = 'Unknown connection';
        n_states[Connection.ETHERNET] = 'Ethernet connection';
        n_states[Connection.WIFI]     = 'WiFi connection';
        n_states[Connection.CELL_2G]  = 'Cell 2G connection';
        n_states[Connection.CELL_3G]  = 'Cell 3G connection';
        n_states[Connection.CELL_4G]  = 'Cell 4G connection';
        n_states[Connection.CELL]     = 'Cell generic connection';
        n_states[Connection.NONE]     = 'No network connection';
    
        console.log(Connection type: ' + n_states[network_State]);
    }
    
    checkNetwork();

    Network-related Events:

    offline

    when the device has no internet connection, this event fires.

    document.addEventListener("offline", onOffline, false);
    
    function onOffline() {
        // Handle the offline event
    }
    
    


    online

    When a device which is not connected to internet changes its state to connected to internet, this event fires.

    document.addEventListener("online", onOnline, false);
    
    function onOnline() {
        // Handle the online event
    }
