remove '\' from string api response aws lambda

Question

I am have AWS Lambda function where I am sending a string as my final response

 let abc= `"phone_exist":"0","calls":"0","lastaction":"0"`
 callback(null,abc);

Output: "\"phone_exist\":\"0\",\"calls\":\"0\",\"lastaction\":\"0\""

here I am unable to understand why "\" has been appended in my string.

Can anyone explain me the reason behind this?
Is their a way using which '\' can be removed so I can get in following form

"phone_exist"="1","calls"="2","lastaction"="3"

\ is an escape character used to escape ". A simple way to get rid of \ is to add {} at the beginning and the and of the string and use JSON.parse(output). This will convert the result into an object and you can use it directly using calls = output.calls — itaintme

You are returning a string, not an object, so Lambda is encoding your string as JSON. What you actually want is most likely this:

let abc = { "phone_exist":"0","calls":"0","lastaction":"0" };
callback(null,abc);

Since those are numbers, you may not want to quote them.

The backslash(\) is an escape character for the special character Double Quote(").

Remove them(") from your original string...

Or ignore them as they are just escape characters.
