क्या कोई मुझे समझा सकता है यह कोड नीचे: 

  var अंक = [99.1, 100, 99.9]; console.log (points.sort ());

... लॉग () s, unsorted array: 

  [100, 99.1, 99.9]  
 सॉर्ट ()  के बाद, सरणी नीचे नहीं होनी चाहिए? 
 
  [100, 99.9, 99.1]  W3schools से: 
 
 
 डिफ़ॉल्ट रूप से, सॉर्ट () पद्धति

मानों को वर्णमाला और आरोही क्रम में तारों के रूप में क्रमबद्ध करता है।

यह स्ट्रिंग के लिए अच्छी तरह से काम करता है ("ऐप्पल" "केले" से पहले आता है)। हालांकि, अगर संख्याओं को तारों के रूप में वर्गीकृत किया जाता है, तो "25" "100" से बड़ा होता है, क्योंकि "2" "1" से बड़ा होता है।

इस वजह से, सॉर्ट () पद्धति गलत का निर्माण करेगी
