Setup
Implement a function that will create an array and fill it with numbers ranging from 1
to n
. The numbers will always be positive.
Examples
spreadNumber(1)
=> [1]
spreadNumber(2)
=> [1, 2]
spreadNumber(5)
=> [1, 2, 3, 4, 5]
Tests
spreadNumber(3)
spreadNumber(6)
spreadNumber(9)
Good luck!

JavaScript:
That creates an Array from 0 to n not from 1 to n ;-)
const spreadNumber = n => Array(n).fill(0).map((_, i) => i+1);
Yeah, i didnt notice its not zero based
Another way:
I think you have an off-by-one error:
spreadNumber(2)
gives[0, 1]
instead of[1, 2]
. Nice and concise, though!Thanks. I didnt notice its zero based
Haskell, many ways
This challenge was simple, so here's a brainfuck solution too. Only works with characters 1-9 as inputs (I have an idea for reading multidigit numbers as input, but I'm on my phone and don't want to type it out).
Javascript, just using a for loop
Codepen
Python
this will not work, it doesn't include the last digit:
spreadNumber(4)
=>[1, 2, 3]
you forgot to add
+1
onn
You are right, I didnt take that in consideration, but it just range(1,n+1)
Clojure short and simple
and some tests...
dart
lol damn, while this is one way, looking at other solutions. I forgot range was a thing.
Late to the party, as always.
Example:
Python
Simple JS
Python, shortest approach
you could've use just
range
like this:
