javascript - Can we stack functions? -


जावास्क्रिप्ट में आप ऐसा कुछ कर सकते हैं? 

  var b = 1212; Var c = b.toString ()। लंबाई;   
 मैं एक कार्यक्रम लिखने की कोशिश कर रहा हूं और अगर मैं यह बहुत आसान कर सकता हूँ मुझे इसके लिए एक लूप की आवश्यकता है।    
  के लिए (var i = 0; i & lt; = 100000 & amp; amp; i.toString ()। लंबाई% 2 == 0; i ++) {/ / मुझे क्या करना है}    
 
 
 हां और नहीं यह संभव है, लेकिन आप की पेशकश की तरह पाश के लिए अंदर की सलाह दी नहीं है। एक और आदर्श कार्यान्वयन कुछ ऐसा होगा ...  
  var len = x.toString ()। लंबाई; के लिए (var i = 0; i & lt; len; i ++) {// do something}   
 ... के लिए अपनी इच्छा के 'i.toString के मूल्य recalculating से बचने के लिए ()। लूप 'प्रत्येक लूप के चलने के लिए।'  
 मैं मान रहा हूं कि वास्तव में आपके इरेटरेटर चर 'i' की स्ट्रिंग प्रस्तुति की लंबाई नहीं लेनी चाहिये जैसा कि ऐसा नहीं लगता किसी भी व्यावहारिक उद्देश्य की सेवा के लिए।
