Having trouble retrieving the value from a JavaScript Array - the elements seem to be organized in an unconventional manner

Question

Having trouble retrieving the value from a JavaScript Array - the elements seem to be organized in an unconventional manner

After running a console.log, I found my array structured like this:

[
  {
    Country: 'US',
    CityName: 'Seattle',
    Region: 'WA',
    PostalCode: '99301',
    StreetName: '3512 Alaska Street'
  },
  to_EmailAddress: { results: [ [Object] ] }
]

Surprisingly, the array length is 1 instead of 2. So, when I call console.log(arr[0]), it displays:

{
  Country: 'US',
  CityName: 'Seattle',
  Region: 'WA,
  PostalCode: '99301',
  StreetName: '3512 Alaska Street'
}

Attempting to access arr[1] gives me undefined.

I'm struggling with how to retrieve the value of to_EmailAddress. Even more so, how can I incorporate

to_EmailAddress: { results: [ [object] ] }

into the first element in the array. Essentially, what I want is:

[
  {
    Country: 'US',
    CityName: 'Seattle',
    Region: 'WA',
    PostalCode: '99301',
    StreetName: '3512 Alaska Street',
    to_EmailAddress: { results: [ [Object] ] }
  },
]

Unfortunately, I am unsure how to achieve this since I cannot even access the to_EmailAddress attribute.

Answer №1

This is an example of a monkey patched property called to_EmailAddress.

const location = [{
    Country: 'US',
    CityName: 'Chicago',
    Region: 'IL',
    PostalCode: '60601',
    StreetName: '123 State Street'
}];

location.to_EmailAddress = { 
    results: []
}

console.log(location);

The above code snippet would output:

[
  {
    Country: 'US',
    CityName: 'Chicago',
    Region: 'IL',
    PostalCode: '60601',
    StreetName: '123 State Street'
},
  to_EmailAddress: { results: [] }
]

You can access it just like any other property in your code:

console.log(location.to_EmailAddress);
