javascript - Need array traversing inside JS filter

Question

static isHomeInternetDeviceInCart(cart: any) {
    let hintDevicesInCart = false;
    if (cart && cart.packages) {
    let devicesFromStorage = JSON.parse(localStorage.getItem("device_list_data"));

    for (const key of cart.packages) {
        if (key.packageType.toLowerCase() == 'data') {
            devicesFromStorage.filter((product:any) => {
         //   for (var i=0; i <= product.items.length; i++) {
                if ((product.items.length > 0) && (product.items[0].deviceSKU == key.device.deviceSKU)
                    || (product.name == key.device.name)) {
                    if(product.isHomeInternetDevice) {
                        hintDevicesInCart = true; 
                    } else {
                        hintDevicesInCart = false; 
                    }
                }
         //   }
        });
        } else {
                hintDevicesInCart = false; 
                break;
            }
       }
    }
    return hintDevicesInCart;
}

I have this code here in Typescript, can I use the for loop inside filter (like the one commented) if there are more than 1 items to be checked. I tried the for loop inside, it doesn't work well, please help me optimizing this code.
