With ES6 you can use findIndex() like this.

var droppableClasses = [{
  key: ".stackDrop-plankovy",
  value: ".card-plankovy"
}, {
  key: ".launchPad-plankovy",
  value: ".card-plankovy"
}];

var index = droppableClasses.findIndex(function(e) {
  return e.key == '.launchPad-plankovy';
})

console.log(index)
