title: Performance and memory differences between C# and Javascript?
body: <p>We have a C# winforms application which models a 3D globe and world state using a large number of object instances, float[] arrays and object references to represent the world state and relationships between objects.</p>
  
  <p>We have been asked to migrate this software to the web and reimplement it in Javascript.</p>
  
  <p>I understand that C# gets jitted to native code, however it sounds as though in recent years there have been huge advances in Javascript performance too.</p>
  
  <p>I am wondering if there is any general information or comparisons of how Javascript fares, performance and memory wise, for raw data manipulation of objects and arrays, compared to .NET or other languages which execute at native performance?</p>
