JAVASCRIPT: GARDEZ LE MEILLEUR ! Paperback – February 19, 2009

French Edition by Douglas CROCKFORD (Author)
Most programming languages contain good and bad parts, but JavaScript has more than its share of the bad, having been developed and released in a hurry before it could be refined. This authoritative book scrapes away these bad features to reveal a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole-a subset you can use to create truly extensible and efficient code.Considered the JavaScript expert by many people in the development community, author Douglas Crockford identifies the abundance of good ideas that make JavaScript an outstanding object-oriented programming language-ideas such as functions, loose typing, dynamic objects, and an expressive object literal notation. Unfortunately, these good ideas are mixed in with bad and downright awful ideas, like a programming model based on global variables.When Java applets failed, JavaScript became the language of the Web by default, making its popularity almost completely independent of its qualities as a programming language. In The Good Parts , Crockford finally digs through the steaming pile of good intentions and blunders to give you a detailed look at all the genuinely elegant parts of JavaScript, * Syntax* Objects* Functions* Inheritance* Arrays* Regular expressions* Methods* Style* Beautiful featuresThe real beauty? As you move ahead with the subset of JavaScript that this book presents, you'll also sidestep the need to unlearn all the bad parts. Of course, if you want to find out more about the bad parts and how to use them badly, simply consult any other JavaScript book.With The Good Parts , you'll discover a beautiful, elegant, lightweight and highly expressive language that lets you create effective code, whether you're managing object libraries or just trying to get Ajax to run fast. If you develop sites or applications for the Web, this book is an absolute must.

Full content visible, double tap to read brief content.

Douglas Crockford is the author of How JavaScript Works. He has been called a JavaScript Guru, but he is more of a Mahatma. He was born in Frostbite Falls, Minnesota, but left when he was only six months old because it was just too damn cold. He has worked in learning systems, small business systems, office automation, games, interactive music, multimedia, location-based entertainment, social systems, and programming languages. He is the inventor of Tilton, the ugliest programming language that was not specifically designed to be an ugly programming language. He is best known for having discovered that there are good parts in JavaScript. That was the first important discovery of the Twenty First Century. He also discovered the JSON Data Interchange Format, the world’s most loved data format.

    5.0 out of 5 stars Une référence javascript qui se lit comme un roman, et qui marque l'esprit
    Reviewed in France on April 20, 2013

    Attention, ce livre n'est pas à considérer comme un manuel d'apprentissage de javascript, mais plutôt comme une référence, un livre rédigé par un expert au franc parlé qui désigne d'un côté les bonnes pratiques de la programmation avec javascript (les "bons éléments"), et de l'autre les "mauvais éléments", et même les "éléments horribles". Cette lecture marque nos esprit pour nous éviter de tomber dans des mauvais travers.

    3.0 out of 5 stars bon livre mais
    Reviewed in France on May 29, 2013
    Format: PaperbackVerified Purchase
    C'est un livre qui mérite le coup d'oeil, il est rempli d'information souvent utile. Mais j'ai un gros reproche, à la fin de la lecture de cet ouvrage vous aurez progressé dans la syntaxe JavaScript mais aucunement dans les bonnes approches pour développer (comment organiser son code...). On a un auteur qui zoome sur les problématiques micros du développement mais nullement sur une approche macro qui est pourtant fondamentale pour faire un code de qualité. D'autre part, il y a beaucoup de dogmatisme chez cet auteur qui me semble bien éloigné de la pratique et de ce qu'il faut faire pour faire du vite sans ménager la qualité. Par exemple le faite de généraliser l'usage de === à la place de == ou bien de déclarer toutes ces variables en tête de fonction, d'un point de vue théorique cela est sans doute valable mais dans la pratique je trouve cela sans intérêt à part de perdre du temps. Si on utilise typeof on ne peut avoir qu'une chaîne en résultat, le === ajoute un test de type sans intérêt mais pourtant recommandé par l'auteur. Je conseille plutôt l'ouvrage "JavaScript, Développez efficacement" à la place.

    Ce livre n'est pas fait pour débuter. Il explique très bien le fonctionnement du langage JavaScript et la façon d'écrire un code efficace et robuste.
