Found trailing undefined in function call JS-W1042
Anti-pattern
Minor
Autofix When an argument is omitted from a function call, it will default to undefined.
It is therefore redundant to explicitly pass an undefined literal as the last argument.
Bad Practice
function hasOptionalParam(a: number, b?: number) {
// ...
}
hasOptionalParam(1, undefined)
Recommended
function hasOptionalParam(a: number, b?: number) {
// ...
}
hasOptionalParam(1)
hasOptionalParam(1, 2)
