How to express JSON as a string in JavaScript

Question

I need help with this. No matter which way I use to convert it to a string, the output is always [object Object]. How can I get the actual content of the JSON object? Thanks!

Answer 1

⏩ Prometheus ⏪ ok so I didn't really check the type of json the api returns. It turns out to be an array json which contains one big object.

=> solution

```
if(window.fetch){
//code here
})
.then(function(myJson) {
// select the object first from
// json data
let output = myJson[0]; <-- this was the problem.

// here output is a normal
// object, so you could access
// all properties such

output.name

// stringify whole object to
// document body

document.write(JSON.stringify(output, null, 2));

```

Hope it helps, happy coding!

Answer 2

convert your JSON data to actual javascript object as follows:

var output = JSON.parse(data);

console.log(output);

you now can do whatever u want with the object.

Hope it helps, happy coding!

⏩ Prometheus ⏪ so I did little debugging and error handling with:

```function handleResponse(response) {
let contentType = response.headers.get("content-type");
if (contentType.includes("application/json")) {
return function(response) {
if (response.ok) {
return response.json()
} else {
return Promise.reject({
status: response.status,
statusText: response.statusText
})
}
}
} else if (contentType.includes("text/html")) {
return function(response) {
if (response.ok) {
return response.text()
} else {
return Promise.reject({
status: response.status,
statusText: response.statusText
})
}
}
}
}
```
and the json still can't be parsed into actual object. please run code in actual browser and let's see. Thanks
