[Typescript] Prettier removes question mark from optional computed class property #6569
Description
Prettier 1.18.2
Playground link
--parser typescriptInput:
const bar = 'bar';
class Foo {
[bar]?;
[1]?;
['baz']?;
}Output:
const bar = "bar";
class Foo {
[bar];
[1]?;
["baz"]?;
}Expected behavior:
Prettier should preserve ? in output. Expected output:
const bar = "bar";
class Foo {
[bar]?;
[1]?;
["baz"]?;
}This only happens when the computed property is a variable.
