Fetch V/S Axios Call

/ axios

const url = 'https://jsonplaceholder.typicode.com/posts'
const data = {
  a: 10,
  b: 20,
};
axios
  .post(url, data, {
    headers: {
      Accept: "application/json",
      "Content-Type": "application/json;charset=UTF-8",
    },
  })
  .then(({data}) => {
    console.log(data);
});
Now compare this code to the fetch() version, which produces the same result:

// fetch()

const url = "https://jsonplaceholder.typicode.com/todos";
const options = {
  method: "POST",
  headers: {
    Accept: "application/json",
    "Content-Type": "application/json;charset=UTF-8",
  },
  body: JSON.stringify({
    a: 10,
    b: 20,
  }),
};
fetch(url, options)
  .then((response) => response.json())
  .then((data) => {
    console.log(data);
  });

To send data, fetch() uses the body property for a post request to send data to the endpoint, while Axios uses the data property
The data in fetch() is transformed to a string using the JSON.stringify method
Axios automatically transforms the data returned from the server, but with fetch() you have to call the response.json method to parse the data to a JavaScript object
With Axios, the data response provided by the server can be accessed within the data object, while for the fetch() method, the final data can be named any variable
