Using the reduce function to return an array

Question

Why is it that when I want to use the push function inside the reduce function to return a new array I get an error. However, when I use the concat method inside the reduce

Answer 1

You can always use destructuring:

var store = [0,1,2,3,4];

var stored = store.reduce(function(pV,cV,cI){
  console.log("pv: ", pV);
  return [...pV, cV];
},[]);

console.log(stored);
