[Compiler Bug]: object's get syntax is missing after compilation.

[Y-Hui]

What kind of issue is this?

• React Compiler core (the JS output is incorrect, or your app works incorrectly after optimization)
• babel-plugin-react-compiler (build issue installing or using the Babel plugin)
• eslint-plugin-react-compiler (build issue installing or using the eslint plugin)
• react-compiler-healthcheck (build issue installing or using the healthcheck script)

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

What version of React are you using?

Thanks for posting, this is a bug. We have not added support for get/set syntax but looks like we missed a todo for this.
