Code quality - Possible unreachable statement

[gsilvapt]

I would like to discuss the possibility of an unreachable statement in the http module:

class HttpApi {
  constructor(options) {
    if (options) {
...
    }
// What I'm interested in discussing:
    if (!this.host)
      throw Error("Host option is required.");
  }

This is line 38 of the file. When can this be reached if there no possibility of creating an empty HttpApi object? Even when we do new HttpApi({host: ""}) it will return the previous error defined with invalid host url.
If you can help me understand when this if statement is reached, I can potentially add one more test to it to make sure this line is covered.

Thanks in advance for your help.
