How to add Object to the array of object in javascript

Question

I'd like to add the Object to the array of object.

My array is in jsfiddle: https://jsfiddle.net/5w4zhw92/

The Expected

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

• Arun P Johny: define sensorType before it is used

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: '' } }];
