About 'Head First' Books
We think of a Head First Reader as a Learner
Learning isn't something that just happens to you. It's something you do. You can't learn without pumping some neurons. Learning means building more mental pathways, bridging connections between new and pre-existing knowledge, recognizing patterns, and turning facts and information into knowledge (and ultimately, wisdom). Based on the latest research in cognitive science, neurobiology, and educational psychology, Head First books get your brain into learning mode.
Here's how we help you do that:
We tell stories using casual language, instead of lecturing. We don't take ourselves too seriously. Which would you pay more attention to: a stimulating dinner party companion, or a lecture?
We make it visual. Images are far more memorable than words alone, and make learning much more effective. They also make things more fun.
We use attention-grabbing tactics. Learning a new, tough, technical topic doesn't have to be boring. The graphics are often surprising, oversized, humorous, sarcastic, or edgy. The page layout is dynamic: no two pages are the same, and each one has a mix of text and images.
Metacognition: thinking about thinking
If you really want to learn, and you want to learn more quickly and more deeply, pay attention to how you pay attention. Think about how you think. The trick is to get your brain to see the new material you're learning as Really Important. Crucial to your well-being. Otherwise, you're in for a constant battle, with your brain doing its best to keep the new content from sticking.
Here's what we do:
We use pictures, because your brain is tuned for visuals, not text. As far as your brain's concerned, a picture really is worth a thousand words. And when text and pictures work together, we embedded the text in the pictures because your brain works more effectively when the text is within the thing the text refers to, as opposed to in a caption or buried in the text somewhere.
We use redundancy, saying the same thing in different ways and with different media types, and multiple senses, to increase the chance that the content gets coded into more than one area of your brain.
We use concepts and pictures in unexpected ways because your brain is tuned for novelty, and we use pictures and ideas with at least some emotional content, because your brain is more likely to remember when you feel something.
We use a personalized, conversational style, because your brain is tuned to pay more attention when it believes you're in a conversation than if it thinks you're passively listening to a presentation.
We include many activities, because your brain is tuned to learn and remember more when you do things than when you read about things. And we make the exercises challenging-yet-do-able, because that's what most people prefer.
We use multiple learning styles, because you might prefer step-by-step procedures, while someone else wants to understand the big picture first, and someone else just wants to see an example. But regardless of your own learning preference, everyone benefits from seeing the same content represented in multiple ways.
We include content for both sides of your brain, because the more of your brain you engage, the more likely you are to learn and remember, and the longer you can stay focused. Since working one side of the brain often means giving the other side a chance to rest, you can be more productive at learning for a longer period of time.
We include challenges by asking questions that don't always have a straight answer, because your brain is tuned to learn and remember when it has to work at something.
Finally, we use people in our stories, examples, and pictures, because, well, you're a person. Your brain pays more attention to people than to things.

About the Book:
The book itself is steady and clear with a variety of projects and written in a friendly tone. It starts from zero, so if you know nothing, you're in the right place. If, like me, you've been working in it and have wondered what some of the parts do at a fundamental level but haven't had a chance to get to the bottom of it, this book will probably cover it. Even though it covers the basic stuff, it also gets into advanced topics. In fact, the last three chapters are worth the cost of the book alone. The chapter on prototypal inheritance upped my game in one evening. No kidding.
My Experience with the Book:
My Full Assessment:
I have read about closures in Java 8 and groovy articles, but I completely understood it only from this book. The coining of the word 'free variables' - variables which are neither local nor global, but declared in the enclosing functions is very good. The definition and explanation that - functions returned from other functions which has also free variables attached to it (in its environment), and those free variables are live variables and not a copy is a very good explanation.
For experienced programmers in other languages (say 5 to 9, which I am ) , you will find this book interesting only if you write answers to the problems and have a pencil with you all the time. Else, it will be a book containing very basic programming constructs which you might know it already. but, if you write the answers, you may find that you made some mistakes and you will wonder why
1. In a chapter - "they build a War Ship Game", the whole code will be divided into Controller, Model and View. This is well explained and would let you think that, even a small peice of code should not hang on the JS file, but go inside a object as a method or a property.
The control should start and end like this : EventHandlers triggered by windows.onload --> Controller -> Model ->View
2. The transition from each topic was very good.
They described about variables and functions (global and local), and then they explained why it has to be inside a Object Literal. and later described why they have to be inside a Contructor (Object object rather than Object Literal), and then they explain why all the commonly used functions and variables should be inside a Prototype, and finally, they explained Prototypical inheritance.
3. All the hanging functions (alert, prompt etc.,,) and objects (console) are properties of window object. Also, all the user defined global variables and functions would be attached to the window object
4. Also, by default "this" would be pointing to window object. Whenever you call a function on a Object Literal or object, the "this" will point to that object instance(that is why you refer the variable with this inside a member method). also, whenever you can a constructor with new, an object will be created, and "this" will point to that object inside the constructor.
5. Also, when a instance is returned by the constuctor, a Constructor.prototype object (an empty object) will be also be attached the object instance.
this will help you to understand prototypical inheritance a lot better in the later chapter.
For aspiring programmers (who were never programmers), I think, this is a very good book to start your career.
