 ### initializeArrayWithRange
 
-Initializes an array containing the numbers in the specified range where `start` and `end` are inclusive with there common difference `step`.
+Initializes an array containing the numbers in the specified range where `start` and `end` are inclusive with their common difference `step`.
 
 Use `Array.from(Math.ceil((end+1-start)/step))` to create an array of the desired length(the amounts of elements is equal to `(end-start)/step` or `(end+1-start)/step` for inclusive end), `Array.map()` to fill with the desired values in a range.
 You can omit `start` to use a default value of `0`.

+### initializeArrayWithRangeRight
+
+Initializes an array containing the numbers in the specified range (in reverse) where `start` and `end` are inclusive with their common difference `step`.
+
+Use `Array.from(Math.ceil((end+1-start)/step))` to create an array of the desired length(the amounts of elements is equal to `(end-start)/step` or `(end+1-start)/step` for inclusive end), `Array.map()` to fill with the desired values in a range.
+You can omit `start` to use a default value of `0`.
+You can omit `step` to use a default value of `1`.

+```js
+const initializeArrayWithRangeRight = (end, start = 0, step = 1) =>
+  Array.from({ length: Math.ceil((end + 1 - start) / step) }).map((v, i, arr) => (arr.length - i - 1) * step + start);
