II not checking both possibilities

My code includes the following-

 if(!code1.startsWith(("<video" || "<img"))){return ...}

The code only checks if code1 doesn’t start with "<video". If the "<video" is false and "<img" is true, it executes the return code.
I am still a learner and hoping for help.

>Solution :

it is not supposed to behave like that; but you can achieve it this way:

if (!(code1.startsWith("<video") || code1.startsWith("<img"))) {
    return ...
}

The code above checks that code string NEITHER starts with <video NOR
<img – so if it starts with either, return …
