import {enablePatches, produceWithPatches} from "immer"
enablePatches();
type DataObject = {
date: Date;

let initialDate = new Date();
let data: DataObject[] = [{date: initialDate}];

let element = draft[0];
let dateBefore = element.date;
element.date = new Date()
element.date = dateBefore;
});
console.log("Patches:", patches) // []
console.log("New Date equal to Initial", newData[0].date === initialDate) // true
console.log("Array equal", newData === data); // expect true but getting falseEnvironment
