When was ECMAScript created?
ECMAScript was created in 1997-06.
Name two scripting languages that can be used in UNIX?
Client-Side- JavaScript, ECMAScript Server-Side- PHP
What are the Recent standardization for java script?
ECMAScript 5 is the latest finished standardisation, but not usable aslong as there are internet explorer browsers out there.
What is Jscript?
JScript is the Microsoft implementation of the ECMAScript scripting programming language specification. JavaScript is used on web pages for scripting, although it can be and is also used in other embedding scenarios.
What is the relationship between java script JScript and ECMA Script?
JavaScript language is officially standardized as ECMAScript (ECMA-262) by European Computer Manufacturers Association (ECMA) International. it is internationally oriented body embraced by Microsoft and holding the standards for C#, CLI and Open XML. Microsoft's own version of JavaScript is JScript and it is mostly compatible with ECMAScript v.3. The intersection between these three variations of the same language is at: # JavaScript 1.5 (without DOM) # JScript as supported by IE6 (still the most widely used browser) # ECMAScript ver. 3 The largest difference between JavaScript and JScript is actually interpreter/runtime related and not language specific. IE6 was known for some notorious performance issues related to its non-generational garbage collector when operating on large object trees.
What is differences between JavaScript and livescript?
JavaScript is LiveScript. It was renamed to gain popularity. The JavaScript name was rejected by then Sun Microsystems who owned the Java trademark. Now the official name is ECMAScript, while it is still commonly referred to as JavaScript. In Internet Explorer it is called JScript. Different names, same language.
What is a JavaScript statement?
A statement in a programming language is a standalone unit of code. In JavaScript, statements generally end with a semicolon or a closing bracket.Examples:// variable statementvar x = 5;// if statementif (x == 0) {...}The ECMAScript language specification lists all the different types of statements permitted in JavaScript. See related links.
What are some words end with the suffix script?
actionscript. adscript. applescript. conscript. ecmascript. javascript. jscript. manuscript. nwscript. playscript. postscript. prescript. rescript. subscript. superscript. transcript. typescript. vbscript. You may check the dictionary for the word definition.
How did javascript begin?
JavaScript started, because Netscape wanted to add a glue language for web designers to its web browser in 1995. Java made it to their web browser a little earlier and quickly gained popularity, so they changed JavaScript's name from the initial LiveScript to the name it has today.
Where can one find more information about Javascript strings?
One can find more information about JavaScript strings from several places. One can look at the JavaScript website. One would also do well to look up JavaScript strings on Stack Overflow, which has many resources for answering questions about programming topics.
What is JavaScript probalem with browsers?
The biggest problem that JavaScript has with the browsers is that the language is not the same between them.This comes from the fact that for a very long time, there was no standardized definition of the language.In 1995, (the early days of the "Browser Wars") Netscape released the first version of JavaScript as part of its ongoing competition with Microsoft's Internet Explorer. As was the case in those day, Microsoft quickly developed a similar client-side language (JScript) for use in its browsers. The languages were similar in function and form, but were not duplicates of one another.This caused a phenomenon to occur know as "code-forking." To get a webpage to display and behave correctly, you had to code it for Netscape, then code it for Internet Explorer, and often you would have to code for separate versions of those browsers. Then a web developer would have to code some means of identifying which browser you were using and route you to the appropriate page.This was a maintenance nightmare. So, the W3C and the European Computer Manufacturers Association created a standardized version of a JavaScript-like, client-side language called ECMAScript in 1997.The latest version of this standard is ECMA-262 ed 5.1. Virtually all manufacturers now claim to be compliant with the standard, although there are legacy quirks. (I won't go so far as to say they're lying--but "compliance" has to be stretched pretty far in this case.)These quirks still haunt us. To get Internet Explorer to register an event handler, for instance, I have to use the addEventListener() method. If I'm working in a Webkit or Gecko browser, I use the ECMA standard, which is attachEvent().There'd be a lot more complaining if it wasn't for the fact that most JavaScript frameworks (jQuery, Ext, Prototype, etc.) hide the complexity of dealing with this from me. In fact, in my opinion as a web developer, this layer of abstraction is exactly why these frameworks are so popular.The W3C is working currently on a new version of ECMAScript that they're calling "Harmony." I have my doubts it will get done, but if it does, it will likely bring the browser manufacturers even closer to true compliance.
What are the rules of wml script?
a. WMLScript is developed based on ECMAScript, which is the standardized version of JavaScript. Thus, WMLScript's language rules are very similar to that of JavaScript.b.c. Semicolons at the End of WMLScript Statementsd. A semicolon is required to end a statement in WMLScript. This is the same as C++ and Java. Note that JavaScript does not have such requirement. In JavaScript, semicolons are optional. The following code is taken from the earlier "Hello World" example. You can see that the two WMLScript statements in this function are ended with semicolons. e.f. extern function helloWorld(){WMLBrowser.setVar("message", "Hello World. Welcome to our WMLScript tutorial.");WMLBrowser.refresh();}g.h. Whitespaces in WMLScripti. Except in string literals, WMLScript ignores extra whitespaces like spaces, tabs and newlines. Hence, the code in the earlier "Hello World" example can be typed in the following way and the result will remain the same: j.k. extern function helloWorld(){WMLBrowser.setVar("message","Hello World. Welcome to our WMLScript tutorial.");WMLBrowser.refresh();}l.m. Case Sensitivity in WMLScriptn. The WMLScript language is case-sensitive. For example, a WMLScript function with the name WMLScript_Function is different from wmlscript_function. So, be careful of the capitalization when defining or referring to a function or a variable in WMLScript. Comments in WMLScriptThere are two types of comments in WMLScript: single-line comment and multi-line comment. To add a single-line comment, begin a line of text with the // characters. To add a multi-line comment, enclose the text within /* and */. These rules are the same in WMLScript, JavaScript, Java, and C++. The WMLScript engine will ignore all comments. The following WMLScript example demonstrates the use of comments: extern function helloWorld(){// This is a single-line comment./* This is amulti-line comment. *//* A multi-line comment can be placed on a single line. */WMLBrowser.setVar("message", "Hello World. Welcome to our WMLScript tutorial.");WMLBrowser.refresh(); // A comment can be placed at a statement's end.}
