Question

I found the way to delete an item of associative array by :

delete array['knownkey'];

but what about delete the whole associative array,I mean just like empty an normal array:

the way to empty an normal array is [I found on the google]:

array = []  //or
array.length = 0 

So,the associative array has the way to empty or remove the all items at once ….

Answer 1

assoc_array = {};

Should set assoc_array to an empty object (aka associative array in JavaScript).

Thanks to garbage collection, there is no real need to empty an existing object. You just go get a new one.
