Check if loops use equality operators (== or !=) in termination conditions. These can lead to infinite loops if the condition is never met exactly. Instead, use relational operators like < or > for safer loop termination.
Using equality operators (== or !=) in loop termination conditions can accidentally cause infinite loops if the condition is never met exactly. Relational operators like < or > are safer and reduce the risk of unintended infinite loops.
Side-by-side examples engineers can pattern-match during review.

}From the same buckets as this rule.
