performance - Does Scala support tail recursion ...

    https://stackoverflow.com/questions/1677419/does-scala-support-tail-recursion-optimization
    Scala does tail recursion optimisation at compile-time, as other posters have said. That is, a tail recursive function is transformed into a loop by the compiler (a method invoke is transformed into a jump), as can be seen from the stack trace when running a tail recursive function.

Tail Recursion - GeeksforGeeks

    https://www.geeksforgeeks.org/tail-recursion/
    Mar 11, 2014 · A recursive function is tail recursive when recursive call is the last thing executed by the function. For example the following C++ function print() is tail recursive.2.4/5

[Proposal] Support tail recursion · Issue #2544 · dotnet ...

    https://github.com/dotnet/csharplang/issues/2544
    Mar 12, 2015 · Yes, the CLR supports.tail. The Roslyn compiler currently has no facility for inserting.tail at all, regardless of what the CLR currently does, however. This is unlike, for example, F#, where tail recursion is leveraged. This comment has been minimized.

Which programming languages support tail recursion ...

    https://www.quora.com/Which-programming-languages-support-tail-recursion-optimization-out-of-the-box
    All functional languages, or languages that encourage a functional style, simply must support tail call optimization, at least for recursive functions. An iterative process in an imperative language uses loops that run by modifying the program state until the state reaches a termination condition, e. g., the loop modifies a counter until it gets to zero or reads from a stream until the read operation fails.

What is tail recursion? Why is it so bad? - Quora

    https://www.quora.com/What-is-tail-recursion-Why-is-it-so-bad
    Dec 17, 2017 · Tail recursion is a special kind of recursion where the recursive call is the very last thing in the function. It's a function that does not do anything at all after recursing. This is important because it means that you can just pass the result of the recursive call through directly instead of waiting for it—you don't have to consume any stack space.

Tail call - Wikipedia

    https://en.wikipedia.org/wiki/Tail_call
    Tail recursion (or tail-end recursion) is particularly useful, and often easy to handle in implementations. Tail calls can be implemented without adding a new stack frame to the call stack . Most of the frame of the current procedure is no longer needed, and can be replaced by the frame of the tail call, modified as appropriate (similar to overlay for processes, but for function calls).

Why doesn't Java have optimization for tail-recursion at all?

    https://softwareengineering.stackexchange.com/questions/272061/why-doesnt-java-have-optimization-for-tail-recursion-at-all
    Unless a language has a special syntax for making a tail call (recursive or otherwise) and a compiler will squawk when a tail call is requested but cannot be generated, "optional" tail-call or tail-recursion optimization will yield situations where a piece of code may require less than 100 bytes of stack on one machine, but more than 100,000,000 bytes of stack on another.

Tail recursion in C# - Thomas Levesque's .NET blog

    https://thomaslevesque.com/2011/09/02/tail-recursion-in-c/
    Tail recursion? What’s that? Some languages, more particularly functional languages, have native support for an optimization technique called tail recursion. The idea is that if the recursive call is the last instruction in a recursive function, there is no need to keep the current call context on the stack, since we won’t have to go back there: we only need to replace the parameters with their new values, …

Tail call recursion in Python - kylem.net

    https://www.kylem.net/programming/tailcall.html
    Recursive tail calls can be replaced by jumps. This is called “tail call eliminination,” and is a transformation that can help limit the maximum stack depth used by a recursive function, with the benefit of reducing memory traffic by not having to allocate stack frames.
