I have a JSON object like this:
var values = {
"email": " ' + fn + ' ", // This field is required to identify existing customers.
"first_name": "email",
"last_name": "email",
"address": "email",
"city": "email",
"state": "email",
"zip": "email",
"dob": "email" // This field must match the following format: YYYYMMDD. This field is also required
};
I am trying to insert:
var fn = 'Tom';
But the variable is not appearing. How can i go about this?
The standard way of using JSON with javascript is to create an object in your application, in this case it may look something like this
var values = {
email: "Tom@whatever",
name: "Tom"
}
You can interact with this object however you like, such as
values.city = "New York";
Then when you are ready to create a JSON object that represents that object, you can use JSON.stringify() MDN docs here
In this case
let jsonString = JSON.stringify(values);
console.log(jsonString);
yields this result:
{"email":"Tom@whatever","name":"Tom","city":"New York"}
This means you don't have to worry about creating a JSON string manually at all!

The problem is that " ' + fn + ' " is treated as a string so fn will never be replaced. What you're after is:
var fn = "Tom";
var values = {
"email": " " + fn + " ", // This field is required to identify existing customers.
"first_name": "email",
"last_name": "email",
"address": "email",
"city": "email",
"state": "email",
"zip": "email",
"dob": "email" // This field must match the following format: YYYYMMDD. This field is also required
};
You can just use email: fn if you dont need the space in the front and back
