Introduction

If you’re working with JavaScript, especially in the context of APIs and JSON data, you might have encountered a situation where attempting to log a JSON string to the console results in an unexpected output. Instead of getting the JSON data you’re expecting, you see something like RESPONSE [object Object]. This can be frustrating, but fear not; we’re here to break down the issue and provide a straightforward solution.

The Problem: Understanding the [object Object] Confusion

When you fetch data from an API, you often receive a JSON object. In your service, you may be using something like this:

In this setup, the response variable is essentially a JavaScript object that represents your JSON data. When attempting to log this object directly with:

You encounter RESPONSE [object Object] instead of the data you want to see. This is because when JavaScript converts an object to a string, it defaults to [object Object], which is not very useful for debugging.

Why It Happens

JavaScript objects don’t automatically serialize to strings in the way you might expect when concatenated with other strings. They require a specific method to print their contents in a readable format.

The Solution: Correctly Logging JSON Objects

1. Logging the Object Directly

Instead of concatenating the string with the object, log the object directly:

This syntax will allow the console to display the entire object structure rather than converting it to a string representation.

2. Logging Multiple Variables

If you want to log several variables simultaneously along with your object, you can do so like this:

This way, you can inspect the other variables in context without losing any details about your JSON data.

3. Using JSON.stringify for Detailed Logs

If you absolutely need the full JSON string representation for some reason, you can use:

This method converts the JavaScript object into a string and formats it nicely for easy readability in the console. The second parameter (null) and third parameter (2) make the JSON output more structured.

Conclusion

With these simple adjustments, you’ll be better equipped to handle the JSON data in your applications and streamline your development process. Happy coding!
