json-parse

Curried function that calls JSON.parse on provided input returning either the parsed JSON or the specified default value if the data fails to parse as valid JSON instead of throwing a SyntaxError.

npm install json-parse --save

You can also use Duo, Bower or download the files manually.

Overview

Similar to try { return JSON.parse } … but more functional and compositionally friendly.
