Question

I’m really struggling to create a valid multidimensional JavaScript array with the following basic format:

var countries = [
  {
    "country": "UK",
    "properties": {"value1", "value2", "value3"}
  },
    "country": "Spain",
    "properties": {"value4", "value5", "value6"}
  }
]

Can someone tell me what I’m doing wrong please?

Answer 1

Please check the below:

var countries = [
  {
    "country": "UK",
    "properties": ["value1", "value2", "value3"]
  },
  {
     "country": "Spain",
     "properties": ["value4", "value5", "value6"]
  }
]

countries is a array, which has 2 element, and the element is an object, whose properties looks like also an array, the array syntax is like [1,2,3]. And be sure { and [ should be pair with } and ].
