Asset Pipeline has become popular thanks to Ruby on Rails which implements it nicely out of the box. In this post I will explain what an asset pipeline is, how you can easily implement it without using Ruby on Rails and why you should consider using it in building a webapp.
Don’t worry, closures is not a complex concept to learn if you break it down into small parts as I’m doing here. What I usually do to keep things in my mind for good is to sketch up a mind map. Yep, a mind map like this one above that has the central subject in the middle and several branches off it. Each branch is a small part of the central subject and this drawing you see is similar to how our brain store information, therefore, it’s a great way to study things.
After this small introduction to mind maps, let’s start with this interesting subject: closures.
First of all, what’s a closure?
for loop to do any operation involving arrays, you should probably have a look below at some “hidden” methods available in ECMAScript5 (the current version on Javascript) to work with Arrays.I say “hidden” because these functions I’m going to show you are available for a while in most of the browsers but most of the people haven’t heard about them or haven’t used them yet.Below are some functions ordered by how frequent I’m likely to use them.

Imagine the situation where you have a single-page app. You start playing around with it and after some actions you decide to click the back button from the browser to go back to a previous state.
Do you think your app is prepared for it?
Dealing with browser history can be a headache specially if your app rely on Ajax calls or you have a single page app. Users love using the back button and developers hate it.
The problem with the browser history in Single-Page applications is that the browser is not able to keep track of the states of your application, differently than the traditional multi-page app where every state is usually bound to a different URL.
So what can we do to let users use the back button and at the same time make sure your application won’t break?
The next-generation of javascript also known as ECMAScript 6 (also called ES6 or Harmony), is bringing us lots of amazing features that you probably will need to know. But instead of you spend too much time learning and researching all of the features I separated a few that I felt are the ones you’ll be probably using in your daily basis.
Don’t worry if you are new to javascript or you’re coming from a server-side language, I believe this is the best time to learn it as ES6 has a much cleaner and friendlier syntax, known as sugar syntax.
