Use this assumption to speed up the spread operator: https://babeljs.io/docs/assumptions#setspreadproperties
Our docs don't use the fast object spread operator, this babel assumption makes code that uses
const x = { ...y }faster. This change is already done in X but I haven't had time to do it here as well.The test case is: open the MUI material docs overview page, then click on the "Button" section. The following graphs show the performance of the first section of code that follows that click event. This section of code is the render functions, and shows an improvement of around 10%.
