Answer 1

Yes string concantenation would work, but you need to convert the input to numbers using parseInt() first.

Here is a demo for your version:

For Ipang's array version, you need push() and join()

These simple projects help embrace your JS skill, keep up 💪

P.S. I don't like your current SoloLearn profile name, it is rude and harrassing.

Answer 2

Illustrate the inputs and expected output please.

About split(), it is a method that is implemented in string class. But <numq2> is a Number not a string, so it's not possible to split s Number, except where the Number is converted to string first.

Answer 3

You still not telling me what expected output should be, given a certain inputs ...

Answer 4

I guess you have two options ...
1. Use an array, fill it up with numbers in range, then use string.join() method to glue the elements into a string.

2. Use an empty string, and concatenate each number in range to the string.

There could be another way, these are just what I had in mind ...
