your syntax is incorrect, try this:

var paris = {
 population: 2.211,
  longitude: 2.3508

Hello , What you're trying to create is an object containing 3 arrays and within each array you're storing a string and a value.

Challenge wanted you to create an object of paris, and an object in javascript is made up of key and value pairs separated by a colon.

Solution :

var paris = {
  population : 2.211e6,
  latitude : '48.8567 N',
  longitude : 2.3508

The above code creates an object names paris with following properties:

  1. population = 2.211e6
  2. latitude = 48.8567 N
  3. longitude = 2.3508

and you can access a property of object like this ,

var pop = paris[population];

The above code will print , 2.211e6 which is the value stored against the key "population" in the object paris.

I hope it answers your question, Happy Coding !
