How to parse String Object with '\n' and \\\

I'm trying to read AWS SNS JSON, but when I try to parse the string object in jsonlog I get a 

SyntaxError:Unexpected token \ in JSON at position 1

I tried to replace '\n' and '\\' but the string is not showing changes

var log = snslogs[i].jsonlog;
logs.push(JSON.parse(`${log}`));

I expect the JSON.parse to create an object.

My JSON.parse accepts the \n at the beginning of the string, not sure if that "position 1" in the error is misleading.

The problem I see is the trailing comma after the last field - that is not allowed in JSON. So your inputs are not valid JSON, but if you really want to accommodate them anyway, try this:

JSON.parse(log.replace(',}$','}'))

or if the initial \n is a problem still, then this:

JSON.parse(log.replace(/\\n/,'').replace(',}$','}'))

You may need to play with the regex if you get other forms of the trailing comma (like with a space after it, etc).
