Javascript is

JavaScript is now developed enough to offer cross-browser, cross-platform solutions from the same codebase, and this has made it viable to develop large scale applications using it. Given that there is a difference between webpages and applications , and that they have different goals and requirements, it is meaningless to point out that a JavaScript application fails when you disable JavaScript. JavaScript is used in millions of Web pages to improve the design, validate forms, detect browsers, create cookies, and much more. It is the most popular scripting language on the internet, and works in all major browsers, such as Internet Explorer, Mozilla, Firefox, Netscape, and Opera. JavaScript is an untyped language, which means that variables do not need to have a type specified. Objects in JavaScript are more like Perl's associative arrays than they are like structures in C or objects in C++ or Java.

JavaScript is a scripting language. You could even say that JavaScript is rather an extension to HTML than a separate computer language. JavaScript is a vast language and it is not possible to teach everything in these 35 tutorial sessions, however, we will cover most of the basics - statements commands and functions. This Javascript tutorial was written for someone who has no programming experience. JavaScript is a scripting language, and besides PERL it may very well be the most deployed scripting langauge in usage today. Where can we find JavaScript besides in browsers?

JavaScript is code too? JavaScript is a little more forgiving than Java. It allows more freedom in the creation of objects. JavaScript is good enough. It is good enough in exactly the way that MS-DOS was good enough.

JavaScript is a very free-form language compared to Java. You do not have to declare all variables, classes, and methods. JavaScript is absolutely the little-language-that-could - continually routing around any of its short-comings and blowing away all of its expectations. I look forward to using it for many, many, years to come.

Web page designers use JavaScript in many different ways. One of the most common is to do field validation in a form. Web designers generally found it more useful for animating images in response to mouse events, validating forms, and other types of DHTML .

Values can be strings, numbers, functions, or other objects. Property names get converted to strings, meaning that the string "25" and the integer 25 boil down to the same thing: Whichever gets declared last overwrites the other. Value: Three comma-separated values in square brackets. The first value specifies the HTML element to display the tooltip at, either by its ID (string, in single quotes), or by a direct reference (no quotes).
