+> Parse JSON with more helpful errors
+
+
+## Install
+
+```
+$ npm install --save parse-json
+```
+
+
+## Usage
+
+```js
+var parseJson = require('parse-json');
+var json = '{\n\t"foo": true,\n}';
+
+
+JSON.parse(json);
+/*
+undefined:3
+}
+^
+SyntaxError: Unexpected token }
+*/
+
+
+parseJson(json);
+/*
+JSONError: Trailing comma in object at 3:1
+}
+^
+*/
+
+
+parseJson(json, 'foo.json');
+/*
+JSONError: Trailing comma in object at 3:1 in foo.json
+}
+^
+*/
+
+
+// you can also add the filename at a later point
+try {
+ parseJson(json);
+} catch (err) {
+ err.fileName = 'foo.json';
+ throw err;
+}
+/*
+JSONError: Trailing comma in object at 3:1 in foo.json
+}
+^
+*/
+```
+
+## API
+
+### parseJson(input, [reviver], [filename])
+
+#### input
+
+Type: `string`
+
+#### reviver
+
+Type: `function`
+
+Prescribes how the value originally produced by parsing is transformed, before being returned. See [`JSON.parse` docs](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Using_the_reviver_parameter
+) for more.
+
+#### filename
+
+Type: `string`
+
+Filename displayed in the error message.
