**Docs**

> constructor(key:string, options:object)

The constructor assign the key for all future operations of this instance 
and we don't need to mention the key again and again

Options includes:
    
- `client`, an instance of some Redis client that exposed all Redis commands as methods names, e.g. [IORedis](https://www.npmjs.com/package/ioredis)

You can set a global client to the library to avoid the need to redefine the client for each new instance, here is an example:

```javascript

import RedisClient from 'ioredis';
import rediss, {RedisList} from 'rediss';

rediss.setGlobalClient(new RedisClient());

let list = new RedisList('someKey');

await list.push('bla bla bla');

````

You can also set the client for specific instance like this:

```javascript

import RedisClient from 'ioredis';
import {RedisList} from 'rediss';

let list = new RedisList('someKey');

list.setClient(new RedisClient());
await list.push('bla bla bla');

````
