Trying to solve this puzzle in JavaScript:
Input: An array containing x amoung of arrays of numbers. Heres example:
[
[1,4],
[6,8],
[10]
]
Expected Output: I would want to run some sort of code to turn it into:
1-4,6-8,10
I’ve tried join(“-“) and tried the same thing within a forEach() loop but can’t quite get it to work
Any help is appreciated!
