Spread vs assign

Abstract

In this article I compare the performance of the spread operator ... and the performance of the assignement operator = in the context of data transformation.

I show that using the spread operator isn't a trivial choice to make and I suggest that immutability and mutation don't have to be mutually exclusive. I also show how one-liner functions can be enriched with the comma operator ,.

What are we measuring?
