/**
 * Creates a Redis instance
 *
 * @constructor
 * @param {(number|string|Object)} [port=6379] - Port of the Redis server,
 * or a URL string(see the examples below),
 * or the `options` object(see the third argument).
 * @param {string|Object} [host=localhost] - Host of the Redis server,
 * when the first argument is a URL string,
 * this argument is an object represents the options.
 * @param {Object} [options] - Other options.
 * @param {number} [options.port=6379] - Port of the Redis server.
 * @param {string} [options.host=localhost] - Host of the Redis server.
 * @param {string} [options.family=4] - Version of IP stack. Defaults to 4.
 * @param {string} [options.path=null] - Local domain socket path. If set the `port`,
 * `host` and `family` will be ignored.
 * @param {number} [options.keepAlive=0] - TCP KeepAlive on the socket with a X ms delay before start.
 * Set to a non-number value to disable keepAlive.
 * @param {boolean} [options.noDelay=true] - Whether to disable the Nagle's Algorithm. By default we disable
 * it to reduce the latency.
 * @param {string} [options.connectionName=null] - Connection name.
 * @param {number} [options.db=0] - Database index to use.
 * @param {string} [options.username=null] - If set, client will send AUTH command with this user and password when connected.
 * @param {string} [options.password=null] - If set, client will send AUTH command
 * with the value of this option when connected.
 * @param {boolean} [options.dropBufferSupport=false] - Drop the buffer support for better performance.
 * This option is recommended to be enabled when
 * handling large array response and you don't need the buffer support.
 * @param {boolean} [options.enableReadyCheck=true] - When a connection is established to
 * the Redis server, the server might still be loading the database from disk.
 * While loading, the server not respond to any commands.
 * To work around this, when this option is `true`,
 * ioredis will check the status of the Redis server,
 * and when the Redis server is able to process commands,
 * a `ready` event will be emitted.
 * @param {boolean} [options.enableOfflineQueue=true] - By default,
 * if there is no active connection to the Redis server,
 * commands are added to a queue and are executed once the connection is "ready"
 * (when `enableReadyCheck` is `true`,
 * "ready" means the Redis server has loaded the database from disk, otherwise means the connection
 * to the Redis server has been established). If this option is false,
 * when execute the command when the connection isn't ready, an error will be returned.
 * @param {number} [options.connectTimeout=10000] - The milliseconds before a timeout occurs during the initial
 * connection to the Redis server.
 * @param {boolean} [options.autoResubscribe=true] - After reconnected, if the previous connection was in the
 * subscriber mode, client will auto re-subscribe these channels.
 * @param {boolean} [options.autoResendUnfulfilledCommands=true] - If true, client will resend unfulfilled
 * commands(e.g. block commands) in the previous connection when reconnected.
 * @param {boolean} [options.lazyConnect=false] - By default,
 * When a new `Redis` instance is created, it will connect to Redis server automatically.
 * If you want to keep the instance disconnected until a command is called, you can pass the `lazyConnect` option to
 * the constructor:
 *
 * ```javascript
 * var redis = new Redis({ lazyConnect: true });
 * // No attempting to connect to the Redis server here.

 * // Now let's connect to the Redis server
 * redis.get('foo', function () {
 * });
 * ```
 * @param {Object} [options.tls] - TLS connection support. See https://github.com/luin/ioredis#tls-options
 * @param {string} [options.keyPrefix=''] - The prefix to prepend to all keys in a command.
 * @param {function} [options.retryStrategy] - See "Quick Start" section
 * @param {number} [options.maxRetriesPerRequest] - See "Quick Start" section
 * @param {number} [options.maxLoadingRetryTime=10000] - when redis server is not ready, we will wait for
 * `loading_eta_seconds` from `info` command or maxLoadingRetryTime (milliseconds), whichever is smaller.
 * @param {function} [options.reconnectOnError] - See "Quick Start" section
 * @param {boolean} [options.readOnly=false] - Enable READONLY mode for the connection.
 * Only available for cluster mode.
 * @param {boolean} [options.stringNumbers=false] - Force numbers to be always returned as JavaScript
 * strings. This option is necessary when dealing with big numbers (exceed the [-2^53, +2^53] range).
 * @param {boolean} [options.enableTLSForSentinelMode=false] - Whether to support the `tls` option
 * when connecting to Redis via sentinel mode.
 * @param {NatMap} [options.natMap=null] NAT map for sentinel connector.
 * @param {boolean} [options.updateSentinels=true] - Update the given `sentinels` list with new IP
 * addresses when communicating with existing sentinels.

 * @example

 * var urlRedis2 = new Redis('//localhost:6379');
 * var urlRedisTls = new Redis('rediss://user:password@redis-service.com:6379/');
 * var authedRedis = new Redis(6380, '192.168.100.1', { password: 'password' });
