Below is the error that I am receiving:
Parsing error: Unexpected token at line 2 col 8 in Atom editor.

Note that I'm currently getting this error on Windows 10.

ESLint Version:
"eslint": "^2.2.0",
"eslint-plugin-react": "^4.1.0"

I have installed linter-eslint in my Atom editor and Global npm ESLint setting is off.

I am quite confused as the error message is not that descriptive. This in no way is hampering my project but I am quite inquisitive as to why I am getting this error in my editor.

ESLint is for validating JavaScript, not JSON.

From the website:

ESLint

The pluggable linting utility for JavaScript and JSX

[emphasis mine]

(You can try your code on the online demo here, and you get the same error)

If you want to use ESLint on a JSON file, you could use a package like eslint-plugin-json.
