説明
Discovered in conversation at https://github.com/microsoft/TypeScript/pull/55892#discussion_r1339658106
class C {
yadda = () => {};
}
class D extends C {
badda() {
super["yadda"]();
}
}
new D().badda()
Currently there is no error for this code; however, if you switched it to a property access, you'd get the error introduced at https://github.com/microsoft/TypeScript/pull/54056.
class C {
yadda = () => {};
}
class D extends C {
badda() {
super.yadda(); // ❌ errors, as expected
}
}
