Have you guys considered a TypeScript standard library?
The web development space today is comprised of a hodgepodge of libraries and tools for doing basic things, from list comprehensions to DOM manipulations to data binding to GET/POST.
It is reminiscent of pre-.NET Windows development days, where a mess of VB and C++ COM objects were floating around to do common 1990s programming tasks, each implementing tasks entirely differently: BSTR or CString or char*? We're hardly any different
today, with $.map, array.map, ko.utils.array*, etc.
Having a standard library greatly improved the state of app development back then, and I think having such a standard library for TypeScript applications would likewise help.
Initially, you could address array filtering/iteration/comprehensions. CoffeeScript skipped this step, and instead chooses to generate inline the same damned loop filtering everytime you use their list comprehensions. Perhaps TypeScript could improve
on that: real list comprehension in the form of a standard library.
