CWE-1046: Creation of Immutable Text Using String Concatenation

MITRE CWE weakness

Description

The product creates an immutable text string using string concatenation operations.

When building a string via a looping feature (e.g., a FOR or WHILE loop), the use of += to append to the existing string will result in the creation of a new object with each iteration, which can be inefficient in comparison with use of text buffer data elements.
