Book Moving – Free eBooks Download JavaScript: la référence - David Flanagan Learn JavaScript Our policy on modern JavaScript JavaScript is an actively evolving language and has changed greatly over the years. In particular, the 6th edition of the language (sometimes known as ECMAScript 2015 or ES6), introduced in 2015, added many new features. At the same time, to maintain backwards compatibility with older websites, old features of the language have been retained, even when they are no longer considered good practice. We think that the features added to JavaScript in ECMAScript 2015 and subsequent versions enable developers to write more readable, reliable, and expressive code, and that it's important to learn about them. The features we teach in this course are stable and have been supported by all major browsers for several years. This topic contains the following modules, in a suggested order for working through them. JavaScript first steps In our first JavaScript module, we first answer some fundamental questions such as "what is JavaScript?" JavaScript building blocks
Getting Out of Binding Situations in JavaScript Most developers don’t know about—or don’t care enough about—binding in JavaScript. Yet this single issue is responsible for a sizeable portion of the questions on most JavaScript-related support channels, and thousands—if not millions—of hairs being tortured away from developer heads every single day. Yet with a little attention to this oft-overlooked subject, you can avoid wasting your time, energy, and patience and move on to more powerful, efficient scripting. Why should we care about binding?#section1 Almost no major object-oriented programming (OOP) languages force you to consider binding. PHP and JavaScript do require you to explicitly state which object you’re accessing, even if it’s the current one. Of course, neither PHP nor JavaScript are actually object-oriented in the traditional sense. In JavaScript, binding is always explicit, and can easily be lost, so a method using this will not refer to the proper object in all situations, unless you force it to. Okay, that’s weird.
Javascript For Designers: Getting on Your Feet Fast Aug 04 2009 Web designers are a special breed – we’re one of a small group of professionals that actively seeks out to improve ourselves and our craft through any means possible. This generally means on our own, from each other, and through an awful lot of ‘guess, test and revise.’ Web design isn’t for the faint of heart or those with any fear of failure. The most daunting ‘learning experience’ for developing developers is to make the jump from the HTMLs and the CSSs of the world to web scripting. It looks good from the outside – all that added interactivity and animation and cool effects and features – oh my. Getting on Your Feet Fast Let’s take a look at bulletproof ways to ease into Javascript at an accelerated pace. The first place I start when looking to learn anything new is on the web – makes sense to learn the web from the web, right? Websites That Teach Javascript Javascript learning sites spend more time on simple logic and processes. Tizag.com W3schools.com About.Com Put It to Use
Named function expressions demystified Introduction Surprisingly, a topic of named function expressions doesn’t seem to be covered well enough on the web. This is probably why there are so many misconceptions floating around. In a nutshell, named function expressions are useful for one thing only — descriptive function names in debuggers and profilers. I’ll start with a general explanation of what function expressions are how modern debuggers handle them. Function expressions vs. One of the two most common ways to create a function object in ECMAScript is by means of either Function Expression or Function Declaration. We can see that when identifier is omitted, that “something” can only be an expression. A somewhat less obvious example of function expression is the one where function is wrapped with parenthesis — (function foo(){}). To demonstrate with examples: You might also recall that when evaluating JSON with eval, the string is usually wrapped with parenthesis — eval('(' + json + ')'). Function statements JScript bugs

I teach computer classes for a living to corporate clients of all levels. If you find this tutorial helpful, please let me know (it's my only reward). What is JavaScript? Javascript is an easy-to-use programming language that can be embedded in the header of your web pages. What's the difference between JavaScript and Java? Actually, the 2 languages have almost nothing in common except for the name. What is Object Oriented Programming? Everyone that wants to program JavaScript should at least try reading the following section. Object-oriented programming consists of Objects, Methods and Properties. The directly accessible bits of information in the object are its properties. Objects and Properties Methods
Google The Best Way to Learn JavaScript Learning something new is scary. For me, the biggest issue with picking up a new skill is that I don’t know what I don’t know. Given that, it’s often useful to find a plan for learning whatever you’re interested in. That’s what this post is: your blueprint, your roadmap, your plan of action for learning JavaScript! You don’t have to worry about finding the best resources, sorting out the bad ones, and figuring out what to learn next. JavaScript is the language of the browser. Before you actually begin learning JavaScript, take a minute to understand what it is and does. JavaScript is not jQuery, Flash, or Java. JavaScript is the language of the browser (not exclusively these days, though). One more note: you’ve heard about jQuery, which is probably the most widely-used JavaScript library. You might even have heard someone say that you should start with jQuery (or another library) and learn JavaScript after. "Level up your skills with our on demand, pragmatic training solution.
