object.push is not a function [Node/Socket.io]

Question

var object = {

}

socket.on('call', function(data){
  console.log(data); // On console: { number: 68, name: 'John' }
  object.push(data);
});

In the console.log I get the object just fine. But the push function doesn't seem to be working.

    object.push(data);
            ^
 
TypeError: object.push is not a function

push is a member function of Array, not Object. You can't "push" anything into an object. Try var arr = []; ... arr.push(data);; — Traveling Tech Guy

object here is an Object, so not have the push function.

If you want to use an object use object[key] = value; or object.key = value;

Array.push in others hand exists.

var object = [];

object.push(value);

Thank you so much, but is it a good idea to have an array with a bunch of objects inside it?

@TwitchClips, in JS you can push objects inside an array. It is not a bad practice.

You can't use push() function for Objects. Actually there is no function named push() for Objects. You need to use an Array if you want to use push.

Hope this code helps.

  var myArray = ['A','B'];
  myArray.push('C');
  console.log(myArray);
  //["A", "B", "C"]

  var myObject = {foo:"bar"};
  myObject.name = "John";
  console.log(myObject);
  //{foo: "bar", name: "John"}
