In JavaScript, we often end up composing one object out of several other objects. Luckily there's a convenient [spread operator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_syntax) which allows us to spread entries from one object to another. Sometimes we only want to include something in the newly created object if a certain condition is met. In this lesson we are going to learn how to conditionally add entries to a JavaScript object using the spread operator.
