JavaScript Tutorials For Beginners

JavaScript is a prototype-based scripting language that is supported by most web browsers and web tools nowadays. One of its most appealing features is its ability to add interactive functions to the inherently static HTML pages. Although it shares its name with the more well-known programming language Java, it is not as powerful as the latter. However, unlike Java, it is easier to use.

JavaScript was first released with the Netscape Navigator 2 browser, and it was Netscape’s LiveScript language which helped create JavaScript. JavaScript‘s ability to function alongside Java seamlessly makes it very popular. This literally means that JavaScript can harness the powerful programming language Java when required, without being a programming language itself. A common example is when JavaScript is deployed to display a data entry form while the processing of the information is rendered by a Java applet or servlet.

JavaScript primarily deals with the web page elements. On the server side, JavaScript is compiled into byte codes, whereas on the client side, it acts as a source code which is embedded into an HTML page. Web pages load faster using High speed Internet service versus a dial-up service.

JavaScript’s syntax is loosely based on the language C, and just like C, it doesn’t possess its own input or output constructs. Additionally, the engine of JavaScript is embedded in a host environment, and as a result, it is reliant on that environment. A typical example of Javascript’s host environment is Web technologies.
