“continue” in cursor.forEach()

Question

I'm building an app using meteor.js and MongoDB and I have a question about cursor.forEach(). I want to check some conditions at the beginning of each forEach iteration and then skip the element if I don't have to do the operation on it so I can save some time.

Here is my code:

// Fetch all objects in SomeElements collection 

var elementsCollection = SomeElements.find();  

 elementsCollection.forEach(function(element){ 

 if (element.shouldBeProcessed == false){ 

 // Here I would like to continue to the next element if this one 

 // doesn't have to be processed 

  }else{

   // This part should be avoided if not neccessary  

   doSomeLengthyOperation(); 

  } 

});

I know I could turn cursor to an array using cursor.find().fetch() and then use regular for-loop to iterate over elements and use continue and break normally but I'm interested if there is something similar to use in forEach().

You can use the below-mentioned code for “continue” in cursor.forEach():-

elementsCollection.forEach(function(element){

 if (!element.shouldBeProcessed) 

return; 

doSomeLengthyOperation(); 

});
