TIL: Object Spread Operator

December 11, 2015JavaScriptES6

The JavaScript spread operator is awesome! Previously when I wanted to merge two objects I would have to pull in underscore or lodash and do something like this.

var obj = _.extend(objectOne, objectTwo, {
  customProp: "You better believe it!",
});

But now with the help of the wonderful babel compiler (along with the stage-2 preset) I am able to do this for the same effect.

var obj = {
  ...objectOne,
  ...objectTwo,
  customProp: "You better believe it!",
};
