Get the data from fetch -> promise -> response

Question

I am trying to post some data to the server but I don\'t know how to get back the response data.

I have the following code:

fetch(url, {
  method: \'POST

There are further methods you call on a fetch response, such as .json(), or .blob(). These methods return a promise which you can call .then() on.

fetch(url, {
    method: 'POST',
    headers: {
        'Accept': 'application/json',
        'Content-Type': 'application/json'
    },
    body: JSON.stringify({
        email: login,
        password: password,
    })
})
    .then(function (a) {
        return a.json(); // call the json method on the response to get JSON
    })
    .then(function (json) {
        console.log(json)
    })

Check out some documentation on using fetch, and some other documentation on how the response object works in a fetch call.
