I am using axios to get an element value that I need to handle it as a string.

const aa = await axios
  .get(`document.querySelector('h2').innerText;`)
  .then((r) => r.data.result.value);

console.log(aa);

then, I need to check for example if the element aa.startsWith("somestring"), but is not accepted, even aa is logged in the console with the expected value.

In general, how could I convert the const result from axios into a string?
