javascript - Create multiple objects of module pattern -

-

कृपया नमूना कोड को नीचे देखें: 

  var sample = (function () { Var a, b; var नमूना = समारोह (एक्स, वाई) {a = x; b = y;}; वापसी {add: function () {a + b;}}}) ();

क्या इसमें कुछ गड़बड़ है?

मैं नमूना वस्तु के कई ऑब्जेक्ट कैसे बना सकता हूं?

मुझे कन्स्ट्रक्टर कैसे लिखना चाहिए? < / P>

मैंने ऑब्जेक्ट को बनाने का प्रयास किया: 

  var s = नया नमूना (1, 2);

लेकिन, यह एक त्रुटि फेंकता है!

मॉड्यूलर पैटर्न एक एकल ऑब्जेक्ट केवल प्रदान करता है इसलिए, आप इसके उदाहरण नहीं बना सकते हैं।

हालांकि, एक वैकल्पिक हल है। उपरोक्त कोड में थोड़ा बदलाव आपको ऑब्जेक्ट बनाने में सक्षम कर सकता है। 

  var नमूना = समारोह (x, y) {var a = x; Var बी = वाई; वापसी {add: function () {return a + b; }}};

अब, मैं कॉल कर सकता हूँ 

  var nine = नया नमूना (4, 5); Var पांच = नया नमूना (2, 3); चेतावनी (nine.add ()); चेतावनी (five.add ());

c# - How to know the number of Threads created and limit the Tasks accordingly -

-
It is very clear that with task as async / await Instead of calling the asynchronous call threads , my question is: Is there a way to monitor threads while completing these tasks? This is because I can decide an optimal number of times for the thread that the thread does not eat too many CPU cycles at the same time (the CPU is intensive to handle the work). We take an example below (output is also mentioned) Although the program is completed in 5 seconds, but it has two threads (id = 1,4 ) if I increase the number of 6 instead of 2, then it creates 4 threads I know that this is the CLR thread OS thread (which is 4 in my machine Are), but I would like to know how they are mapped O (with actions) and use the same CPU. Is there any way to get it? Test code Fixed zero main (string [] args) {RunTasksWithDelays (). ); } Static async Task Run Task with Dislay () {Stopwatch S = Stopwatch. Startup (); Console.light line ("thread id =" + thread.content.trade.manag...
