Original: I Hardcoded a Recursion Demo Into My Binary Converter and I Regret Nothing

Short summary

A developer built a decimal-to-binary converter with a hardcoded call-stack animation for input 5, using staggered setTimeout calls to visually demonstrate how recursion unwinds. The animation shows frames stacking and popping in reverse order, building intuition that text explanations can't. The author acknowledges the hack's limitations—it only works for 5, has no cleanup logic, and breaks with duplicate frame IDs.

  • Hardcoded a visual call-stack animation for decimalToBinary(5) using setTimeout
  • Animation shows frames stacking top-down and resolving bottom-up, mirroring real recursion
  • Author admits it's not good engineering but argues it teaches recursion better than prose
