-Returns an array of numbers in the arithmetic progression starting with the given positive integer and up to the specified limit.
+Creates an array of numbers in the arithmetic progression, starting with the given positive integer and up to the specified limit.
 
 - Use `Array.from()` to create an array of the desired length, `lim/n`, and a map function to fill it with the desired values in the given range.
 
 ```js
 const arithmeticProgression  = (n, lim) => 
-  Array.from({ length: Math.ceil(lim / n) }, (v, i) => (i + 1) * n );
+  Array.from({ length: Math.ceil(lim / n) }, (_, i) => (i + 1) * n );
 ```
