The Advantages of JavaScript

JavaScript is a client-side language that runs on any web browser. The scripting language is used in conjunction with HTML to present dynamic web pages to end users. JavaScript has several advantages over HTML, because it can be coded to interact with the user after the page has already loaded in the web browser. - JavaScript works in conjunction with HTML to provide dynamic configurations and layouts for readers on a website. HTML is static, and the tags displayed on the screen cannot be edited once the code is loaded in the web browser. However, with JavaScript, the tags' properties, methods and members can be manipulated. For most websites, the JavaScript language is used to change properties dependent upon the user's input while running the web application.
- JavaScript is also the language used to create popups for users. The online ad industry uses JavaScript to display new windows or tabs in the browser that contains an ad. This allows website owners to advertise their business product or service on another user's website. Popups have become an annoyance on websites that have an exorbitant amount of new windows using JavaScript. However, popups are useful for people who need to display an alert or navigate the user to another website without exiting the existing web application.
- Ajax is a newer technology that incorporates JavaScript with secure database record retrieval. Ajax is based on JavaScript, and it allows programmers to retrieve records without refreshing the page. This means that users with a slow connection to the Internet do not need to reload the page, which can take several seconds with a page that has large amounts of images and data to display. Ajax retrieves records while the main layout of the page stays in the browser.
