What is the reason JSON.parse fails to convert a string into a JSON object?

I attempted to convert a string into a JavaScript object using JSON.parse, however, it seems to be unsuccessful.

After trying various methods, I did not receive any output in the console.log and no error messages were displayed.

JSON.parse(`{'exp': '1', 'input': '1d6404f66ed3d72e', 'iterate': 'no'}`); 

Update

In my actual code, I am passing the value from an object.

console.log(JSON.parse(future.onIOPub.data['text/plain']))

Answer №1

Upon executing this code snippet, you will encounter the following output:

Uncaught SyntaxError: Unexpected token ' in JSON at position 1

The reason for this error is due to the usage of single quotes. JSON strictly requires double quotes, as outlined in the specifications.
