Crockford s book is already considered one of the classic JS books and I agree Not because its complete it only touches ECMAScript core, not even DOM , or particularly good at making things seem simple it probably makes them look overcomplicated Its because it approaches JavaScript in a completely different way than probably any other book you ve read It broadens your horizons as a JS developer, makes you think differently And as soon as you finish it, you haven t only learned a few facts Crockford s book is already considered one of the classic JS books and I agree Not because its complete it only touches ECMAScript core, not even DOM , or particularly good at making things seem simple it probably makes them look overcomplicated Its because it approaches JavaScript in a completely different way than probably any other book you ve read It broadens your horizons as a JS developer, makes you think differently And as soon as you finish
For an experienced developer who s hacked things together while glancing at an online reference, JavaScript The Good Parts seems like a good place to start learning the language properly As the title indicates, the book consists of Crockford s opinions about how to use JavaScript s better features and avoid the bad ones Being a relative JS novice, it s hard for me to evaluate his judgements, but I m glad to now have at least someone s best practices to work with Crockford s descriptions of J For an experienced developer who s hacked things together while glancing at an online reference, JavaScript The Good Parts seems like a good place to start learning the language properly As the title indicates, the book consists of Crockford s opinions about how to use JavaScript s better features and avoid the bad ones Being a relative JS novice, it s hard for me to evaluate his judgements, but I m glad to now have at least someone s best practices to work with Crockford s descriptions of JavaScript s odder crummier features were entertaining My reading notes include items like, typeof NaN number yields true Derp JavaScript s syntax looks familiar to most programmers, but this can lead to incorrect assumptions about how it works For instance, JavaScript uses curly brace delimited blocks like Java , but does not use block level scoping You can access object properties using a dot notation that looks like a met
Returning to serious JS programming after a long hiatus When you pick up the rhino book O Reilly s definitive tome on JS and thumb through it, you notice that it is written from the perspective of JS being introduced to the industry It s all functional programming, browser oriented, and thought of as an API to make the monkey dance , rather than a serious programming languag
I don t think the importance of JavaScript in our current world can be overstated Nor can the work of Douglas Crockford to legitimize JavaScript by extracting and promoting subsets of the language which are brilliantly designed In the case of JSON, he recognized JavaScript s object notation as a wonderful and concise way to describe data structures In my opinion, JSON is vastly superior to XML in every way.I came to this book after watching Crockford s wonderful companion lecture at Google Te I don t think the importance of JavaScript in our current world can be overstated Nor can the work of Douglas Crockford to legitimize JavaScript by extracting and promoting subsets of the language which are brilliantly designed In the

As an experienced JavaScript programmer, I was looking around for introductory books for my friends who are just starting their programming journeys so this book came up in the usual lists of modern JavaScript books.This book was a huge disappointment The authors ability to turn even simple concepts into confusing railroad diagrams coupled with explanations that do not make any sense even to someone well versed in the subject is absolutely astounding It feels like the book doesn t quite know w As an experienced JavaScript programmer, I was looking around for introductory books for my friends who are just starting their programming journeys so this book came up in the usual lists of modern JavaScript books.This book was a huge disappointment The authors ability to turn even simple concepts into confusing railroad diagrams coupled with explanations that do not make any sense even to someone well versed in the subject is absolutely astounding It feels like the book doesn t quite know what it wants to be It starts with a disclaimer of not being intended for beginners and then proceeds to spend a long time explaining the syntax for
Many programming books are funny because their authors make jokes Why s Poignant Guide to Ruby comes to mind Javascript The Good Parts, however, is the first programming book that has ever made me laugh out loud when the author wasn t telling a joke Case in point undefined and NaN are not constants They are global variables, and you can change their values That should not be possible, and yet it is Don t do it.Any developer who has ever written Javascript is likely to have been confound Many programming books are funny because their authors make jokes Why s Poignant Guide to Ruby comes to mind Javascript The Good Parts, however, is the first programming book that has ever made me laugh out loud when the author wasn t telling a joke Case in point undefined and NaN are not constants They are global variables, and you can change their values That should not be possible, and yet it is Don t do it.Any developer who has ever written Javascript is likely to have been confounded by a number of its pitfalls, and in many cases I think one s first instinct is to assume that you ve done something wrong Crockford clarifies that Javascript s heritage as the language of the web browser gives it a number of unique deformities, and he labels them as such pretty unambiguously I like that Honesty makes it easier for developers to move forward and write better code.Chapter 5, on Inheritance, was the most helpful in terms of understanding how to write large applications in a way that provides mos
4.0 Opened my eyes to how JavaScript really works, but had some bad bugsI ve been using JS for a while now, just throwing stuff together and getting things working, copying patterns observed elsewhere At times I saw some unfamiliar structures particularly of the anonymous functions that return functions getting invoked immediately variety, etc , but chose to ignore them All the while I assumed it was actually an OO language How wrong I was.This was quite helpful for someone familiar with 4.0 Opened my eyes to how JavaScript really works, but had some bad bugsI ve been using JS for a while now, just throwing stuff together and getting things working, copying patterns observed elsewhere At times I saw some unfamiliar structures particularly of the anonymous functions that return functions getting invoked immediately variety, etc , but chose to
My new JavaScript reference This book takes a stand in defining the good features of JavaScript banning the rest as evil or not useful It even introduces a linter that enforces the above It does all of this in 150 pages or so The good parts are actually described in the first 100 pages That s it.The book is not for complete novices to
