Match variable to JSON content and return data

I have a variable that contains a country name.

var country = 'belgium';

I have a JS data structure:

var countryCoords = {
  argentina: '56 100',
  belgium: '100 200'
}

How do I get the co-ordinates for Belgium?

You can extract them using country as the key:

console.log(countryCoords[country]);

Objects support bracket notation and dot notation...

var country = 'belgium';

var countryCoords = {
  argentina: '56 100',
  belgium: '100 200'
}

countryCoords[country]; // '100 200'
countryCoords.belgium; // '100 200'
