...mind a böngészo frissítése, mind egy új biztonsági szoftver, illetve biztonsági patch befolyásolhatja a JavaScript beállításokat. Ezért az a javaslat, hogy ellenorizzük le, hogy engedélyezve van-e a JavaScript, amikor problémákat észlel. Ezen felül, ha JavaScript beállításai 'Prompt' állásban vannak, értesítéseket fog kapni, amikor potenciálisan veszélyes scripteket tölt le különbözo hirdetéseket tartalmazó oldalakról. 

The Real Name is ECMAScript

JavaScript's official name is ECMAScript.

ECMAScript is developed and maintained by the ECMA organization. 

ECMA-262 is the official JavaScript standard.

The language was invented by Brendan Eich at Netscape (with Navigator 2.0), and has appeared in all Netscape and Microsoft browsers since 1996.

The development of ECMA-262 started in 1996, and the first edition of was adopted by the ECMA General Assembly in June 1997.

The standard was approved as an international ISO (ISO/IEC 16262) standard in 1998.

The development of the standard is still in progress.
This is an object-oriented scripting language used to enable programmatic access to computational objects within a host environment. Although also used in other applications, it is primarily used in the form of client-side JavaScript, implemented as part of a web browser, providing enhanced user interfaces and dynamic websites. JavaScript is a dialect of the ECMAScript  standard and is characterized as a dynamic, weakly typed, prototype-based language with first-class functions. JavaScript was influenced by many languages and was designed to look like Java, but to be easier for non-programmers to work with.JS is a lightweight programming language,  is usually embedded directly into HTML pages,  JavaScript is an interpreted language (means that scripts execute without preliminary compilation), Everyone can use JavaScript without purchasing a license.
Java and JavaScript are two completely different languages in both concept and design!
Java (developed by Sun Microsystems) is a powerful and much more complex programming language - in the same category as C and C++.
    * JavaScript gives HTML designers a programming tool - HTML authors are normally not programmers, but JavaScript is a scripting language with a very simple syntax! Almost anyone can put small "snippets" of code into their HTML pages
    * JavaScript can put dynamic text into an HTML page - A JavaScript statement like this: document.write("<h1>" + name + "</h1>") can write a variable text into an HTML page
    * JavaScript can react to events - A JavaScript can be set to execute when something happens, like when a page has finished loading or when a user clicks on an HTML element
    * JavaScript can read and write HTML elements - A JavaScript can read and change the content of an HTML element
    * JavaScript can be used to validate data - A JavaScript can be used to validate form data before it is submitted to a server. This saves the server from extra processing
    * JavaScript can be used to detect the visitor's browser - A JavaScript can be used to detect the visitor's browser, and - depending on the browser - load another page specifically designed for that browser
    * JavaScript can be used to create cookies. A JavaScript can be used to store and retrieve information on the visitor's computer */
