JavaScript is somewhat minimalist in its approach. Many familiar elements, such as explicit data types (int, String, REAL), are missing or have been substantially simplified. However, JavaScript also provides many powerful object-oriented constructs which greatly simplify program organization. In this way, JavaScript has the expressive power of languages such as C or Java, while alsoContinue reading “Comparing JavaScript”

JavaScript is an action-oriented model of the World Wide Web. Elements of a Web page, such as a button or checkbox, may trigger actions or events. When one of these events occurs, a corresponding piece of JavaScript code, usually a JavaScript function, is executed. And that function, in turn, is composed of various statements whichContinue reading “Action Oriented JavaScript”

Objects are just arrays of properties. However, properties are accessed somewhat differently than array elements. New properties added to an object at any time. It is possible because properties usually only use the left side of the array. The array creation functions organized into two categories: those that place the enhanced properties at the end,Continue reading “JavaScript Arrays”

Javascript is structured and interpreted object-oriented language. JavaScript gives you access to the entire Web page. You can modify properties of the page or any element of the page. You can also create new documents or update parts of a form. JavaScript is designed to be easy to learn and convenient to use by almostContinue reading “JavaScript Use and Functions”
