It can be expensive to instantiate a new object, and doing so inside a loop is typically an error. Instead, create the object once, before the loop.

Noncompliant Code Example

for (var i:int = 0; i < 10; i++) {
  var temp:MyObj = new MyObject();  // Noncompliant
  //...
}

Compliant Solution

var temp:MyObj = new MyObject();
for (var i:int = 0; i < 10; i++) {
  //...
}
