Showcase of my take on fizzbuzz for a friend that is learning some programming languages. Try at https://play.nim-lang.org/#ix=2prQ

fizzbuzz.nim

import sequtils, tables, strutils

const gameRange = (1..100).toSeq
const gameRuleTable = {
 3: "Fizz",
 5: "Buzz"
}.toOrderedTable

proc gameRules(x: int): string =
  for k,v in gameRuleTable.pairs:
    if x mod k == 0:
      result.add v
  if result.len == 0:
    result = $x
  
const fizzBuzz = gameRange.map gameRules
const gameOutput = fizzBuzz.join("\p")
echo gameOutput
