The Expected

var sensors = [
{ id: 'led', name: 'LED', type: { port: '', path: '' } },
{ id: 'temp', name: 'TEMP', type: { path: '' } },
];

Answer 1

It's already working you just need to declare the variable before using it.Declare sensorType first then use it.

var sensorType = {
    sender: {
        port: '',
        path: ''
    },
    receiver: {
        path: ''
    }
    };
var sensors = [
    { id: 'led', name: 'LED', type: sensorType.sender },
    { id: 'temp', name: 'TEMP', type: sensorType.receiver }
    ];

    console.log(sensorType.sender);
    console.log(sensors);

Answer 2

Just change order of statements in your code. Declare sensorType object first.

 var sensorType = { sender: { port: '', path: '' }, receiver: { path: '' } }; var sensors = [ { id: 'led', name: 'LED', type: sensorType.sender }, { id: 'temp', name: 'TEMP', type: sensorType.receiver }, ]; console.log(sensorType.sender); //Returns Object {port: "", path: ""} console.log(sensors); //[{ id: 'led', name: 'LED', type: { port: '', path: '' } },{ id: 'temp', name: 'TEMP', type: { path: '' } }];
