Unfortunately, these good ideas are mixed in with bad and downright awful ideas, like a programming model based on global variables. Considered the JavaScript expert by many people in the development community, author Douglas Crockford identifies the abundance of good ideas that make JavaScript an outstanding object-oriented programming language-ideas such as functions, loose typing, dynamic objects, and an expressive object literal notation. This authoritative book scrapes away these bad features to reveal a subset of JavaScript that's more reliable, readable, and maintainable than the language as a whole-a subset you can use to create truly extensible and efficient code. HTML provides the structure and content of a web page, CSS provides the visual styling, and JavaScript provides the dynamic interactivity.Most programming languages contain good and bad parts, but JavaScript has more than its share of the bad, having been developed and released in a hurry before it could be refined. Together, HTML, CSS, and JavaScript form the backbone of the modern web, and are essential skills for web developers. JavaScript is typically used in combination with HTML and CSS to create dynamic and engaging web pages.

JavaScript is used to add interactivity to a web page, such as responding to user actions, updating content on the fly, and creating animations. JavaScript is a scripting language that allows you to create dynamic and interactive web pages. CSS makes it easy to maintain a consistent look and feel across multiple pages of a website.

CSS is used to control the layout, colors, fonts, and other visual aspects of a web page, separate from the HTML content. HTML tags define the headings, paragraphs, lists, links, images, and other elements of a web page.ĬSS (Cascading Style Sheets) is a stylesheet language used for describing the look and formatting of a web page. It is a markup language, which means that it uses tags to describe the structure and content of a web page.

HTML (Hypertext Markup Language) is the standard language used to create web pages.
