If you want some or every and not forEach, they are there -- use them.
No exception required.
I've found myself multiple times in a situation where I needed the index
of the first element responding to some conditions. I solved it the
following way:
var index;
array.some(function(e, i){
if(someCondition(e)){
index = i;
return false;
}
return true;
})
It works, but felt a bit awkward. It's a hack on .some because there is
no other way to stop an iteration in other array methods.
Also spending hours on debugging because someone confused "some" for
"every" (mixed the meaning of true/false) isn't fun.
var index;
array.forEach(function(e, i){
if(someCondition(e)){
index = i;
throw StopIteration;
}
})
would look more explicit in my opinion.
