            Does Dart feature Tail Call Optimization (TCO)?
            Asked 2021-Feb-25 at 08:55

            I wanted to try out in Dart some algorithms and patterns from Functional Programming, but a lot of them rely heavily on recursion, which might incur in serious memory leaks without Tail Call Optimization (TCO), which isn't mandatory for when implementing a language.

            Is there an official statement on this topic from the Dart team or something about it in the documentation? I could probably figure out if this is currently present in the language by using Dart's Dev Tools and Profiling, however this way I would never be able to know the Dart team's intentions with respect to the topic, hence the raison d'être of this question.

            Dart does not support tail-call optimization. There are no current plans to add it.

            The primary reason is that it's a feature that you need to rely on in order to use, otherwise you get hugely inefficient code that might overflow the stack, and since JavaScript currently does not support tail call optimization, the feature cannot be efficiently compiled to JavaScript.

            ngx-bootstrap typeahead http request returns object Object
            Asked 2021-Jan-11 at 18:28

            I'm trying to build a typeahead off a service that returns JSON however my code is returning [object Object] instead of the values. What am I doing wrong? It seems like something to do with my typeaheadoption not correctly mapping to result however I'm not sure why this would happen. This comes from the HTTP Async example from ngx-bootstrap: https://valor-software.com/ngx-bootstrap/#/typeahead

            The problem is that the typehead doesn't know how to retrieve the value from the field name 4. region since it is invalid according to its internal implementation! A proper solution is to declare your interface like follow:

            QUESTION

            Is async code in a Promise always an antipattern?
            Asked 2020-Dec-24 at 03:16

            I see from this question that it can be an antipattern to mix Promises with async code.

            Does this, however, apply in all cases?

            I can't see an easy way to avoid combining them in the following code:

            • It's an alternative to setInterval which waits for an invocation to complete before scheduling the next one
            • However, unlike recursive setTimeout, it does not constitute an open memory leak in browsers that don't yet support TCO

            Does this code embody an antipattern? And, if so, how can I remedy it without introducing a memory leak?

            See, in particular, line 10: new Promise( async (resolve) => {

            —this seems very non-idiomatic, but I don't see another way to accomplish: wrapping an await statement in a while loop per se, dispatching it, and returning a handle to abort the loop.

            Answered 2020-Dec-24 at 03:16

            The problem that the other question was warning about, and that could be a problem here, is that if the inside of the async callback passed to the Promise constructor awaits something that rejects, the Promise will hang instead of rejecting. Your current code will not result in f ever rejecting, but setRepeatedTimeout were to carry out a task which may reject, you'd get an unhandled rejection and permanent hanging:

            Will this depend on phase_step having a single solution?

            Kind of, but a bit stronger still: It depends on phase_step being deterministic, which means, not leaving any "choice points". A choice point is a future path to be explored; not necessarily one that will produce a further solution, but still something Prolog needs to check.

            For example, this is deterministic:

            This did the trick using your example. I'm asuming all your data follows the same format.

            You'll need to create a clean "all in" column to join df1 with df2. After doing two joins, clean the useless rows and update the values of the NAs using your "all in" column.

            By steps
            1. Create new column to separate.
            2. Separate the rows with multiple values.
            3. Remove the "gene_id " so you can have your clean "all in" column to join.
            4. Join by one column then by the other one. Order doesn't matter.
            5. Filter rows without any match.
            6. Update your NAs
            7. Remove new_col because you don't need it anymore
