oxc/bad-comparison-sequence Correctness
What it does
This rule applies when the comparison operator is applied two or more times in a row.
Why is this bad?
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.
Example
javascript
if ((a == b) == c) {
console.log("a, b, and c are the same");
}How to use
To enable this rule in the CLI or using the config file, you can use:
bash
oxlint --deny oxc/bad-comparison-sequencejson
{
"rules": {
"oxc/bad-comparison-sequence": "error"
}
}
