The Continuation-Passing Style in JavaScript
In JavaScript, a callback is a function that is passed as an argument to another function and is invoked with the result when the operation completes.

JavaScript is a very function-oriented language. As we know, functions are first class objects and can be easily assigned to variables, passed as arguments, returned from another function invocation, or stored into data structures. A function can access variable outside of it. But what happens when an outer variable changes? Does a function get the most recent value or the one that existed when the function was created? Also, what happens when a function invoked in another place - does it get access to the outer variables of the new place?

Figure caption for images on Jekyll sites - single line with Markdown
Markdown makes writing blog posts simple and fast, but sometimes that simplicity comes with limitations. Recently on updating this blog theme, I'm intend to include images in the post with captions, and there wasn’t a straightforward way using Markdown. While adding an img tag is very easy with Markdown, I would have to do some fiddling to inset the caption.
