Is like `Array.join()` but with an additional argument of `end`(is equal to `separator` by default) which is used to separate the second to last and last items in the array. Returns `""` when the array is empty and the first item when the length of array is 1.

const join = (arr,separator = ',',end = separator ) => { const join = (arr, separator = ',', end = separator) =>
return arr.reduce((acc,val,i) => { arr.slice(0, arr.length - 1).join(separator) + end + arr[arr.length - 1]
return i == arr.length - 2 ? acc + val + end : i == arr.length - 1 ? acc + val : acc + val + separator
},'')
