Definitely, but it works without the slice(), too:
var filtereds, items, limit, k;
items = new Array(1000).join("-").split("");
limit = 3;
k = 0;
filtereds = items.filter(function( val, i, orig ) {
if ( true ) {
if ( ++k === limit ) {
orig.length = 0;
}
return true;
}
});
console.log( filtereds );
// [ '-', '-', '-' ]
