What Is: Javascript

Javascript is an object-orientated programming language that is supported by modern internet browsers.

Developed back in 1995 by Brendan Eich, it was initially called LiveScript. JavaScript is undoubtedly a cornerstone of web development and the user experience.

It is used alongside CSS and HTML by programmers to code web pages. But while HTML is used to influence content appearances, JavaScript is what makes a website interactive. Essentially, it is the component that brings a page to life.

One of the most common examples of JavaScript comes from pop-up boxes. If you’ve ever hovered over an image or text box to be greeted by a pop-up, it’s probably due to a Javascript framework.

Other examples of Javascript include altering the layout. This could be done by minimising or enlarging certain areas, or through animations following a click. Without Javascript, users can still see text and navigate through the website. However, it would lack any dynamic features, essentially losing all appeal of the modern technology.

The coding appearance of JavaScript features doesn’t differ too much from HTML. In fact, it is usually placed into the HTML file (although it doesn’t have to be). The language embraces the use of angle brackets to input the code, starting with:

< SCRIPT LANGUAGE=”JavaScript” > (without the spaces)

The coding that follows can be used to create calendars, animations, and various interactive features. Of course, the specific nature of the exact file will dictate what follows on the backend page of website coding.

Essentially, JavaScript alters the behaviour of a web page. It runs in real time, and can also be used to alert users when they make mistakes – such as entering a typo in a text box. Rather than reloading the page, the interactive element acts independently. This gives the user has a smoother interaction with the site.

Unlike HTML, JavaScript can be a little difficult to learn. However, mastering JavaScript brings many benefits. It enables programmers to overcome the limitations encountered by systems designed for beginners. Ultimately, the interaction gives users a far more immersive experience, and can have a huge impact on the success of the site.

The benefits of using Javascript:

  • Javascript codes enhance HTML frameworks by making a website more interactive and entertaining.
  • It gives the user a greater sense of control over those interactions.
  • Pages become more versatile, allowing them to serve an even greater sense of purpose.
  • Websites instantly look more professional, which reflects well on a business.
  • It’s a coding language used almost universally by modern web browsers. It can be embedded into HTML and ASP files, giving the programmer immense control.
  • JavaScript features can be used to promote a specific aspect of the webpage.

Interactive features coded through JavaScript will only be displayed when the user’s web browser is capable of viewing it. If those extensions aren’t enabled, those elements of the page will remain dead. Those add-ons are free to download, however, and are naturally installed on most modern devices. Nonetheless, it is worth considering, especially when testing a new item.
