how to setstate for the success result

[Laxman980]

new Compressor(file, {
    quality: 0.6,

    // The compression process is asynchronous,
    // which means you have to access the `result` in the `success` hook function.
    success(result) {
        // in this place how we define the setstate. i did setimagedata(result), it show error
    },
});

Try console.log(result) in the success hook to see what the result is.
