// Handles mix-cased strings and numbers with option for setting order
const sortObjectArray = ({ arr, field, order = 'desc' }) => {
   arr.sort(function(a, b) {
      const fieldA = typeof a[field] === 'string' ? a[field].toLowerCase() : a[field]
      const fieldB = typeof b[field] === 'string' ? b[field].toLowerCase() : b[field]

      let result
      if (order === 'desc') {
         result = fieldA > fieldB ? 1 : -1
      } else {
         result = fieldA < fieldB ? 1 : -1
      }
      return result
   })
   return arr
}

let arr = [

console.log(arr3)
/*
[
{ age: 54, name: "Peter" },
{ age: 34, name: "John" }, 
{ age: 25, name: "jake"}
