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