oxc/bad-comparison-sequence Correctness
何をするか
This rule applies when the comparison operator is applied two or more times in a row.
なぜ問題なのか
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.
