Footnotes 50 and 51 from Piya Tan's analysis of SN 55.24:


  
  Of joyous wisdom,” hāsa,pañña, alt tr “of laughing wisdom” (from hasa, “laughter, mirth, joy”). “Here one
  with much joy [laughter], mirth, contentment and gladness perfects the virtues: this is joyous wisdom” (Pm 21.17/
  2:199 f). Comys mention hāsa,paā (joyous wisdom), javana,paā (quick wisdom) [see foll n], tikkha,paā
  (sharp wisdom, which cuts off all defilements) and nibbedhika,paā (penetrating wisdom, by which one maintains
  dispassion toward all formations) (DA 3:391-393, 4:84-86; MA 4:84; SA 1:120-123, 2:85 f; AA 2:85; ThaA 3:106 f;
  NmA 1:231 f; cf PmA 3:640 on hasa,paā)
  “Of quick wisdom,” javana,pañña. This refers to one who quickly understands that the 5 aggregates are all impermanent, suffering and non-self (Pm 21.18/2:200). See prev n.
