D3.JS datamaps country name variable

Question

I want to enter the country name as a variable but I can't.

var interval_1=window.setInterval(function() {
  var name = "USA";
  map.updateChoropleth({
  name : colors(Math.random() * 10),
  });
}, 2000);

Answer 1

What you want is to use a variable as a key in a JavaScript object literal. This has already been answered here: Using a variable for a key in a JavaScript object literal

This would give the result you expect:

var interval_1=window.setInterval(function() {
    var name = "USA";
    var country = {}
    country[name] = colors(Math.random() * 10)
    map.updateChoropleth(country);
}, 2000);
