Tag closures

One of the principles every programmer tries to follow is DRY (Don't Repeat Yourself). With currying, we'll see how applying this to our functions is pretty simple and useful.

If JavaScript does not have classes, how do you implement inheritance? That is probably one of the questions every developer has asked themselves. In this post, we will try to answer it once and for all.

A closure is when a function is able to remember and access a lexical scope, even when that function is executed outside of that lexical scope.

Today I wanted to write about a really interesting topic that plays a huge role in modern computing. Understanding a bit about it will be a great help when it comes to grasping some advanced JavaScript concepts.

I am especially excited about this topic because it took me a while to understand the concept, since I came from other programming languages where it was not common. So if I can help you understand it, that would be awesome.
