I need to replace imagesrc with the value stored in this object. However when I run:

if(data['results'][res]['entities']['media'][0][media_url]) {

    imagesrc = data['results'][res]['entities']['media'][0][media_url];

}

I get the error:

Cannot read property '0' of undefined

How can I run my condition so that I don't get errors if something is undefined?
