Question

Short code for checking if a variable also exists inside an array is needed.
Im thinking something like this:

   var category='cars';
   if (in_array(category, some_array)){
       do stuff!
   }

Is there any such function in js?

Thanks

There’s no native “in_array”-function in JavaScript (as in PHP), check out this solution:
