I need a Set that has the API similar to the Set in Java.
This implementation:
http://jsclass.jcoglan.com/set.html
Requires the use of RequireJS, which requires my Java brain to twist too much at the moment.
Posting a function that is the functionality for Set would be a great answer. Or a link to a Google Set or some other tech giant who has created this code already.
What about Google's Closure? The name confused me but it has a set.
In my opinion whatever java.util.Set can achieve can be done using simple javascript object. I don't see why you need additional library:
// empty set
var basket = {};
// adding object to set
basket['apple'] = true;
basket['banana'] = true;
basket['orange'] = true;
basket['apple'] = true;
// iterating through set contents, should print:
// apple
// banana
// orange
for(var fruit in basket)
console.log(fruit);
// check if an element exist
if(basket['pineapple']) {
console.log('has pineapple');
} else {
console.log('no pineapple');
}
// remove element from set
delete basket['apple'];
Object.toString. In Python, I used set more than I used arrays, and I really miss it. I suppose that Python's sets aren't real sets either, they are hash tables implicitly indexed by the memory addresses of their values, but at least I didn't have to manage keys or hash functions myself. I still haven't found a solution that I really like.
