javascript - How do I fetch JSON in React Native

Question

I was trying this

//...
const getMetadata = async () => {
  try {
    let response = await fetch(
      'https://favradio-stats.glitch.me/metadata'
    );
    let json = await response.json();
    return json;
  } catch (error) {
    console.error(error);
  }
};

console.log(getMetadata);
//...

returns [Function getMetadata]

if I call getMetadata() instead of getMetadata, will get the undesired result:

{"_U": 0, "_V": 0, "_W": null, "_X": null}

Why and what is wrong with that code?

You could try:

const getMetadata = async () => {
  try {
    let response = await fetch(
      'https://favradio-stats.glitch.me/metadata'
    );
    let json = await response.json();
    return json;
  } catch (error) {
    console.error(error);
  }
}
.then((result) => {
  console.log(result)
});

getMetadata();
