## Available functions:

The goal of this test is to create a working code against 4 simple fake APIs. We are simulating two requests coming from users (two arrays of strings).  

You have to do the following for each string:

1. Translate the source language using `translation.translate()` (Or fetch the same data from cache if available / store in cache if not).

2. Get a binary (a fake MP3) for a TTS speech for the translated text using `speech.speak()` (Or fetch an existing URL from cache if available / store in cache if not).

3. Store the binary data into storage and get a URL for said data using `storage.pipe()`.

4. Respond to the user by calling `respond()` for each request with the data in the following format:

```js

 const response = {

   translations: [], // Add all the translated strings to this array in the same order as they came in

   speech: [] // Add all the speech URLs to this array in the same order as the translations

 }

```

Each fake API respons with a Promise and simulates the real world by taking some time to respond.

### Cache

```js

cache.getItem("someKeyHere"); // Returns a promise that resolves to a string if found or undefined if not.

cache.setItem("someKeyHere", "someDataHere"); // Returns a promise that resolves after the cache has been stored.

```

### Translation

```js

translation.translate("English Source Text"); // Returns a promise that resolves to a string containing the translation as a string.

```

### Speech

```js

speech.speak("Texto fuente en español"); // Returns a promise that resolves to a readable stream that will stream binary data (async).

```

### Storage

```js

storage.pipe(stream); // Returns a promise that resolves to a fake URL once the stream has ended. A unique URL for each source text will be provided.

```
