Is there a way to extract both a and b from the array?

I just started learning programming and I'm currently working on creating an API call to use in another function. However, I've hit a roadblock. I need to extract values for variables a and b separately from the response of this API call:

import axios from "axios";

async function main() {
  await axios
    .get('https://api.blocknative.com/gasprices/blockprices?confidenceLevels=99', {
      headers: {
        Authorization: 'key'
      },
    })
    .then(function(response) {
      const a = response.data.blockPrices[0].estimatedPrices[0].maxFeePerGas;
      const b = response.data.blockPrices[0].estimatedPrices[0].maxPriorityFeePerGas;
      return [a, b]
    });
};

main().catch(console.error);

Can anyone guide me on how to achieve this? I've looked into topics like scope, block, and destructuring but I'm still unable to find a solution. Thank you for your assistance!

Answer №1

If you make the main function return a promise and handle its resolve, you can access variables a and b.

import axios from "axios";

function main() {
  return await axios.get(
    "https://api.blocknative.com/gasprices/blockprices?confidenceLevels=99",
    {
      headers: { Authorization: "key" },
    }
  );
}
main()
  .then(function (response) {
    const a = response.data.blockPrices[0].estimatedPrices[0].maxFeePerGas;
    const b =
      response.data.blockPrices[0].estimatedPrices[0].maxPriorityFeePerGas;
    return [a, b];
  })
  .catch(console.error);
