Suck on Use a try block in the appropriate place to catch an error. Include a catch block with error as the parameter.

I am on the node.js basics tutorial. Objective test = "Using try and catch"

It starts off as this:

Question: Something bad is going to happen. Use a try block in the appropriate place to catch an error. Include a catch block with error as the parameter.

Code: var jsonString = 'This is not a JSON String'; var jsonObject = JSON.parse(jsonString);

What I added (complete) but still failing: var jsonString = 'This is not a JSON String'; var jsonObject = JSON.parse(jsonString);

try { jsonObject; } catch (error) {

};

Any thoughts here?

The variables have to be in the Try block! The block is gonna try to parse jsonString as a JSON string which is not. 

try {
 var jsonString = 'This is not a JSON String';
var jsonObject = JSON.parse(jsonString);

} catch (error) {

}

Bil is right on with this answer. I added a console.log(error) to the catch and it passed. Take that as you will.

Remove the semicolon at the end of the catch block

var jsonString = 'This is not a JSON String';
var jsonObject = JSON.parse(jsonString);

try {
  jsonObject
} catch (error) {

}
