Question

What is JavaScript and how does it work?

Answer

For many companies setting up a website for the first time or maintaining an existing one, web development and the processes involved may seem like a foreign concept to those unfamiliar to it. With a diverse library of web development terminology and the coding skills needed, it is easy to get confused by this area of website design and maintenance. This blog post will focus on the web development term, JavaScript.

What is JavaScript?

JavaScript is a client side interpreted scripting language used by many web developers. Along with HTML and CSS, it is considered as being one of the essential technologies of web development and web content production. It was designed and developed in order to allow web developers to make web pages more interactive and to help them in creating web applications. JavaScript’s application programme interface (API) allows it to work with text, arrays, dates and regular expressions but does not include graphic features. However, it is important not to confuse JavaScript with Java. Although similar in that they both come from C and C++ programming languages, Java is a more advanced programming language than JavaScript.

 

How does it work?

JavaScript runs within an Internet browser on a visitor’s computer and doesn’t require constant downloads on the company’s website. There is no special software or code needed to run JavaScript. This is due to the fact that JavaScript is prewritten and is available as a plug in.

In order for it to run, a web developer has to place a JavaScript code on to HTML pages. When a user requests a HTML page with JavaScript in it, the script is then sent to the user’s browser and the Internet browser deals with it from then on. This is as long as the user’s browser supports JavaScript. If it does, the JavaScript code will run automatically without any intervention or action from the user promoting a seamless user experience.

Depending on which way you wish for the JavaScript code to run, whether it is with a web page open, when a click or drag is made on a page element or when a form is submitted this can be specified from the outset.

As a scripting language, JavaScript is generally quite easy to implement and manage. Once it is placed within the HTML page and is supported by a user’s Internet browser then it will create a seamless and functional experience for your users.
