Unknown JavaScript syntax when defining an object

I came across some JavaScript syntax I haven't seen before. Can someone help point me in the right direction, I'm not even sure what I could google to learn more :/

$.variable = function() {
  return a(b, [{
    key: "setPeriod",
    value: function(t) {
      this.variable.period = t;
    }
  }, {
    key: "location",
    get: function() {
      return "earth";
    }
  }])
}

$.variable.setPeriod("test");
$.variable.location;

My question is what is this structure where an object is defined via a list. Also not sure what the difference between value and get is. Any help would be appreciated.

Here's an example of a snippet:

Here my guess about what happens to this list of objects :

var o = s([{
  key: "attribute",
  value: "default"
}, {
  key: "getAttribute",
  value: function () {
    return this.attribute;
  }
}, {
  key: "setAttribute",
  value: function (value) {
    this.attribute = value;
  }
}]);

console.log(o.getAttribute());
o.setAttribute("custom");
console.log(o.getAttribute());

function s (members) {
  var o = {};
  members.forEach(function (member) {
    o[member.key] = member.value;
  });
  return o;
}

I guess the framework needs to preprocess the object's members for some obscure reasons related to the framework internal mecanism.
