How to loop through all the properties of an object in an array?

Question

JavaScript

data: function () {
          return {
           address: [
              {
                flat: 0,
                house: 0,
                street: 0,
                settlements: 0,
                municipality: 0,
                edge: 0
              },
              {
                flat: 0,
                house: 0,
                street: 0,
                settlements: 0,
                municipality: 0,
                edge: 0
              }
            ]
    }
},
methods: {
          paintLine() {
            for(var prop in this.address[0]) {
                console.log(prop + ':' + this.address[0].prop);
            }
          }
}

Displays all undefined values. How to fix ?

Answer 1

Obviously, you are trying to get the 'prop' field from the object. upd. Don't forget to check if these are private properties of the object (hasOwnProperty)
