Dependent Object Type Check Javascript Seems Redundant

Is there a better way of doing this?

If I do this:

    if(typeof someObject[bar][foo] == "function"){
        // Do something
    }

I get a someObject[bar][foo] is not an object error which it's referring to someObject[bar] if bar does not exist. This means that the code assumes you know that someObj[bar] is defined. So my solution was was this:

if(typeof someObj[bar] === "object"){
      if(typeof someObject[bar][foo] == "function"){
        // Do something
    }
}

If we want to make an effort to reduce code lines and to make good, clean, readable code then looks redundant and ugly. Is there a better way of doing this without having to go through two if points? I realize that it's not that big of a deal, but I'm wondering if there is a better way.
