Question

I am getting accross this fiddle link about knockout cascading dropdownlist

If I refer to this code:

viewModel.years = ko.dependentObservable(function() {
    return Enumerable.From(makeModelList).Select(function(it) {
      return it.year;
    }).OrderBy(function(it) {
      return it.year;  
    }).Distinct().ToArray();
}, viewModel);

at the line the Enumerable.From().Select…

It is very much as a Linq expression call from C#, is it Javascript or Jquery ?

thanks if you have any link about it.

Cheers all

I advise you to look at underscorejs or it’s fork lodash. Coming from a .NET background myself, I know that LINQ is great and I really love it. However, those libraries I mentioned do pretty much the same thing but:

• have a much wider adoption in the JavaScript world
• receive more frequent updates
• and are just more well known by the community

I did the mistake and used one of those LINQ libraries and I really wish I hadn’t because of the things that I outlined.
