## Remarks
The project uses some ES6 features that are supported by the current version of Node (7.7.4 by the time writing).
I've tried to keep the project as simple as possible, therefore there are no external dependencies. I could've used some and it would lead to the following changes in the code:
1. Using a Promise library like bluebird would let me replace some `Promise.resolve()` usages with `.map`:
Without bluebird:
```
return this.httpClient.get(url)
.then((rawData) => {
const parsedData = JSON.parse(rawData);
return Promise.resolve(parsedData);
});
```
With bluebird:
```
return this.httpClient.get(url)
.map(JSON.parse);
```
2. There would be no need in writing `HttpClient` since such implementations are already in the npm registry.
3. The project would be probably transpiled to ES5 using Babel in order to ensure compatibility with older environments.
4. ES6 `import` and `export` keywords would be used instead of Node's module system based on `require` and `module.exports`.
