JavaScript: Building Rich and Interactive Web Applications

x = x x = x x = x x = x

Variables = Used to store data temporarily Functions = Blocks of code that perform a specific task Arrays = Ordered collection of values Objects = Used to model real-world entities

Document Object Model (DOM) = Enables interaction with HTML elements Element objects = Part of the DOM tree providing properties and methods Web applications = Platform where JavaScript is widely used React Native = Framework for building mobile applications

DOM manipulation = Modifying web page content and structure User interfaces = Built using JavaScript's interaction with the browser's DOM Electron = Framework for building desktop applications Microcontrollers = Programmed using JavaScript for robotic applications

Variables = Containers that hold values Functions = Reusable blocks of code that perform specific tasks Arrays = Collections of values stored in a single variable Objects = Collections of key-value pairs representing complex data structures

Variables = Declared using let, const, or var keywords Functions = Denoted by the function keyword and can receive input data Arrays = Created using square brackets [] and support various manipulation methods Objects = Represent complex data structures with key-value pairs

Variables = Containers that can hold different values and are loosely typed Functions = Reusable blocks of code that can output a result and receive input data Arrays = Collections of values that can contain different types and support manipulation methods Objects = Complex data structures represented by key-value pairs

Variables = Hold values and can be reassigned with different values Functions = Perform specific tasks and can be declared in various ways Arrays = Store collections of values and provide methods for manipulation Objects = Represent complex data structures through key-value pairs
