discontinuous-range

|
|
===================
|
||
|
|
|
||
|
|
```
|
||
|
|
DiscontinuousRange(1, 10).subtract(4, 6); // [ 1-3, 7-10 ]
|
||
|
|
```

this is a pretty simple module, but it exists to service another project
|
||
|
|
so this'll be pretty lacking documentation.
|
||
|
|
reading the test to see how this works may help. otherwise, here's an example
|
||
|
|
that I think pretty much sums it up
|
||
|
|
|
||
|
|
|
||
|
|
###Example
|
||
|
|
```
|
||
|
|
var all_numbers = new DiscontinuousRange(1, 100);
|
||
|
|
var bad_numbers = DiscontinuousRange(13).add(8).add(60,80);
|
||
|
|
var good_numbers = all_numbers.clone().subtract(bad_numbers);
|
||
|
|
console.log(good_numbers.toString()); //[ 1-7, 9-12, 14-59, 81-100 ]
|
||
|
|
var random_good_number = good_numbers.index(Math.floor(Math.random() * good_numbers.length));
|
||
|
|
```
