What is JavaScript®?

6 Examples of popular features of web pages that can be created with JavaScript® include user interfaces such as pop -up windows, drop -down menus and images that turn over them over them. The most common form of this scripting language is JavaScript on the side of the client that runs on the user's own computer, also known as a client computer rather than on a computer server. The features written in this language are often added to the HTML code used to create a website, and on the client side, JavaScript® is usually part of the web browser environment, which means that the web browser interprets and performs code. There is also a version on the side of this scripting language server, which has increased in popularity with the release of faster products such as Node.js.

This scripting language is often used to create more dynamic websites than can only be achieved using HTML code. For example, JavaScript® can be used to add current data calculationsAnd and the time on a website or to create a user interface that changes the color or other characteristics of displaying based on user events. It can also be used to verify the forms of filled and send on the website. In addition to its use on the website, it is also used for various other purposes, including as an application platform for a graphical user interface in some web browsers, and as an embedded scripting language in a wide range of applications such as Adobe's Acrobat, Yahoo! Widgets and Widgets Dashboard Apple.

JavaScript® was developed by Netscape and was published in 1995 as part of the Netscape Navigator web browser. This scripting language corresponds to the EcmaScript language standard and is considered a dialect of EcmaScript. EcMascript is a SCR on the client side of the Language, which has been standardized by the international organization ECMA International, an international organization that develops and maintains standards for information and communication systems.

DevelopmentJ JavaScript® has been influenced by programming languages ​​such as C, C ++, Scheme and Self, and is sometimes referred to as a functional programming language. One of the reasons for this designation is that the JavaScript® function is first -class, which means that they are treated as objects. This means that functions can be manipulated by different programming commands such as variables or values. It is important not to confuse this scripting language with the Java programming language, which was also affected by C and C ++, but in most respects it is quite different.
