oxc/bad-comparison-sequence Correctness

✅ This rule is turned on by default.

무엇을 하나요

This rule applies when the comparison operator is applied two or more times in a row.

왜 문제인가요?

Because comparison operator is a binary operator, it is impossible to compare three or more operands at once. If comparison operator is used to compare three or more operands, only the first two operands are compared and the rest is compared with its result of boolean type.
