Repro steps

const state = {
  get doubleValue() {
    return 2 * 2;
  }
};

In the above code, doubleValue uses get syntax, and after compilation, it loses the get keyword and becomes an ordinary function. In this case the compiler should skip compilation until this syntax is supported.

I know that some syntaxes are currently unsupported by the react compiler, can we know what syntaxes are currently unsupported and in process?

How often does this bug happen?

Every time
