JavaScript Best Practices with syntax and examples JavaScript best practices are guidelines for writing clean, maintainable, and efficient JavaScript code. By following these best practices, developers can ensure that their code is easy to read, understand, and debug. Code Organization - Keep code organized by breaking it down into smaller functions and modules. - Use...
Javascript Error Handling and Debugging with syntax and examples Error Handling: - Error handling is the process of anticipating, detecting, and resolving errors in a web application. - Error handling ensures that web applications can handle unexpected situations and provide a better user experience. - Error handling uses try-catch blocks, error objects, and error events...
Javascript Web Storage and APIs with syntax and examples Web Storage: - Web Storage allows web applications to store data locally within the user's browser. - Web Storage provides two mechanisms for storing data: localStorage and sessionStorage. - Data stored in localStorage persists even after the browser is closed, while data stored in sessionStorage is...
Javascript Async Programming and Callbacks with syntax and examples Async Programming: - Async programming allows code to run asynchronously, improving performance and responsiveness. - Async programming uses callbacks, promises, and async/await to handle asynchronous operations. Callbacks: - Callbacks are functions passed as arguments to other functions. - Callbacks are executed when an operation is complete....
Javascript DOM and Events with syntax and examples DOM (Document Object Model): - The DOM is a tree-like structure that represents the HTML document. - The DOM allows JavaScript to interact with the HTML document. - The DOM provides methods and properties to manipulate the HTML document. DOM Syntax: - Selecting elements: - document.getElementById('id') -...
Javascript Objects and Arrays with examples Objects: - Objects are collections of key-value pairs. - Objects are used to store and manipulate data. - Objects can contain properties and methods. Object Syntax: - Object declaration: - const objectName = { key: value, key: value }; - Accessing properties: - objectName.key - Adding properties: - objectName.newKey...
Control Structures: - Control structures determine the flow of a program's execution. - JavaScript has several control structures: - Conditional statements (if/else, switch) - Loops (for, while, do-while) - Jump statements (break, continue, return) Conditional Statements: - If/else statements: - if (condition) { code } - if (condition) { code } else { code }...
In this module, we will explore the fundamental building blocks of JavaScript: variables, data types, and operators. Variables: - Variables are containers that store values. - In JavaScript, variables are declared using the let, const, or var keywords. - let and const are block-scoped, while var is function-scoped. Data Types: - JavaScript has several data...
JavaScript is a high-level, dynamic, and interpreted programming language that is primarily used for client-side scripting on the web. It was created by Brendan Eich in 1995 while he was working at Netscape Communications Corporation. JavaScript is often used to add interactive elements to websites, create web applications, and develop desktop and mobile applications. History...
