I've built a countdown directive for a website I'm working on, and it actually functions just fine. It simply parses a given date, splits the total time remaining until that date up into Day, Hour, Minute, & Second components places them into the DOM, and then increments down until 0 is reached. ...

Welcome to JavaScript, where all things look fine but are actually half broken. :D
Finally I think I've found a way to 'create' classes that can inherit
I think there's a saying that goes like "Composition over inheritance". That's because composition...

This will be my first code review for Rust as I am just learning it. I am trying to move from python to a systems programming language so this is a bit of a challenge for me.
Here is my code.

I would at least return the exception too if there is any.

Here's the second draft of my ADT stack code which I posted here before after carrying out most of the improvements suggested there.
I decided to expose a function called resize_stack to adjust the size of the stack as desired by the user instead of doing it automatically.

One edge case you're missing is how to handle null. isEmpty(null) will fail because Object.getOwnPropertyNames(null) will throw TypeError: can't convert null to object.
What does the code do (tested basic, no errors, usecase):

converts each to JSON
store it in another directory, with the same basename as source file
... with .yin replaced by .json

Can there be too many follow-up questions?
Considering that some follow-up questions can get massively down-voted, I think the answer is Yes, there can be too many follow-ups (at least in a certain amount of time). I say this is based on my observations of community reactions to certain follow-u...

I have written a NodeJS module and its tests to generate a URL, shorten it with Bitly, insert the short link in a tex file, compile these tex files to PDF and then merge them into one.
