Instructions

• Solve all problems using JavaScript

Problems

1. Write a function that returns an array with the first n powers of 2. Call it twoPow.

2. Use twoPow and Array.prototype.reduce to the sum of the first 10 powers of 2.

3. Describe this call signature:

   A simple newline delimited JSON protocol.

   Receiving Usage:

     protocol = require('./json-protocol');

     // parsing data
     parser = protocol.StreamParser();
