Expression expected error on logical operator after checking if instanceof GenericClass<T> #13856
Description
Prettier 2.7.1
Playground link
--parser typescriptInput:
export class Foo<T> {
}
function sample(error: unknown) {
if (!(error instanceof Foo<'some-type'> || error instanceof Error) || !error.message) {
return 'something';
}
}Output:
SyntaxError: Expression expected. (5:43)
3 |
4 | function sample(error: unknown) {
> 5 | if (!(error instanceof Foo<'some-type'> || error instanceof Error) || !error.message) {
| ^
6 | return 'something';
7 | }
8 | }Expected behavior:
3 |
4 | function sample(error: unknown) {
5 | if (
6 | !(error instanceof Foo<'some-type'> || error instanceof Error) ||
7 | !error.message
8 | ) {
6 | return 'something'
7 | }
8 | }It works if I wrap Foo<'some-type'> with parentheses and then prettier formats it like expected behavior (also removes edit: problem occured again on reformat (obviously)( )) but I think it should work without wrapping.
It works if I split that logical OR into separate statements (I know this is not logically the same as above, just for an example)
!(error instanceof Foo<'some-type'>) ||
!(error instanceof Error) ||
!error.message
