In this lesson in our journey through the world of the ES6 syntax, we look at the Spread Operator. We learn very quickly upon looking at the makeup of the spread opertor, that it bears the same "..."' structure that we learned in the previous lesson, the rest parameters. The spread operator is different. When using the spread operator, we are able to unpack an array, as opposed to the rest parameter, which allows us to collect elements passed in an array. We learn that the spread operator can only work in-place. So, the spread operator can only work as an argument for a function or in an array literal. Understanding this helps in distinguishing the difference between the spread operator and rest parameters.
