catch errors from JSON.parse (from nodeschool workshop)

test.js

// Some invalid JSON will be available on process.argv[2].
// Build a function called `parsePromised` that creates a promise,performs `JSON.parse` in a `try`/`catch` block, and fulfills or rejects the promise depending on whether an error is thrown.**Note:** your function should synchronously return the promise!
// Build a sequence of steps like the ones shown above that catchesany thrown errors and logs them to the console.

JSONdata = process.argv[2]

function parsePromise(data) {
    return new Promise(function(fulfill, reject){
        try{
            parsedData = JSON.parse(data)
            fulfill(parsedData)
        } catch(error){
            reject(error)
        }
    });
}

// Podemos usar then pq a função retorna uma promise
parsePromise(JSONdata).then(null, function onReject(error) {
    console.log(error.message)
})
