HTML doesn’t describe the layout of the page. It describes the relative structure of the content like which is the title, which is the heading, which is the sub-heading and which is the paragraph. How this content has to be shown and rendered will be decided by styling and it is called style sheets. In one way you can say that HTML is the flesh and bones of a person and CSS is the clothing on the person that overrides the default skin. Cascading Style Sheets tell browsers how to display HTML tags. These style rules override the default display rules that browsers have for HTML tags.
While HTML provides the relative content structure for a website and CSS allows you to control the presentation of the website, the JavaScript programming language gives you the tools that you need to alter the behavior of different elements that are found on a website page. With this tool, you can add a layer of interactivity to the CSS and HTML elements on your website, which is highly recommended if you want to appeal to the customer in terms of a good user interface and user experience.
Most modern websites come with a menu button that can be clicked to display a selection of areas on the website that you can navigate to. The menu button usually reveals a small menu on the side of the page, which adds interactivity to the page itself. All of this is powered by JavaScript and can make your website appear to be more modern and sophisticated.
JavaScript is a scripting language that works on computing something and presenting those results dynamically on the browser. It is used both on client-side and sever-side and makes the web-pages interactive, modifies website content and presents various results on the web-page. PHP as a script used to use to do some of the scope of work that JavaScript is doing now. Therefore, people get confused between the two languages. They usually think PHP is a server-side language and JavaScript as client-side language as it was only executed in web browsers. But after the recent V8, Node and other frameworks, JavaScript is capable of doing a lot of things PHP used to do. Since we can handle both front-end and back-end through JavaScript now, it is considered as more powerful than PHP now.
It is the most popular lightweight, interpreted compiled programming language. It is also known as a scripting language for web pages. It is well-known for the development of web pages, many non-browser environments also use it. JavaScript can be used for client-side developments as well as server-side developments. This is why it is such an important language to learn in today’s world.
Hope this is useful, thank you.
