Course Curriculum
Section 1. Course #1 Javascript Basics
Introduction to JavaScript
JavaScript is a high-level, interpreted programming language that is widely used for web development. It allows developers to add interactivity and dynamic behavior to websites. JavaScript is a lightweight language that can be embedded directly into HTML documents. It runs on the client side, meaning that it is exec...
Conditional Statements and Loops
Introduction to Conditional Statements Conditional statements are used in programming to make decisions based on certain conditions. They allow us to control the flow of the program and execute specific statements or blocks of code based on whether a condition is true or false. In JavaScript, the most common conditional statement is the if...
Functions and Scope
Introduction to Functions In JavaScript, functions are the building blocks of code. They allow us to encapsulate reusable blocks of code that perform a specific task. Functions are an essential part of JavaScript programming and play a vital role in simplifying our code and making it more organized. To define a function in JavaScript, we use...
Arrays and Objects
Arrays are an essential part of programming, especially in JavaScript. They allow us to store and manipulate collections of data. Imagine you are a basketball coach and you want to keep track of your team's players. You can use an array to store their names. Here's an example array of basketball players: const basketballPlayers = ["Kobe B...
DOM Manipulation
Welcome to the Introduction to DOM Manipulation! In web development, DOM manipulation refers to the process of changing and updating the HTML structure and content dynamically using JavaScript. The DOM (Document Object Model) represents the web page as a tree-like structure, where each element is a node with properties and methods. DOM manip...
Events and Event Handling
Introduction to Events In JavaScript, events are actions or occurrences that happen in the browser. These can be triggered by the user, such as clicking a button or submitting a form, or they can be triggered by the browser itself, such as the page finishing loading or a timer expiring. Events are an integral part of building interactive web a...
Form Validation
Form validation is a critical aspect of web development, as it ensures that user input is accurate and valid. Without proper validation, users may submit incorrect or incomplete information, leading to errors or issues later on. As a web developer, it is essential to understand the importance of form validation and its role in creating a better us...
AJAX and APIs
AJAX (Asynchronous JavaScript and XML) is a powerful technique used in web development to create more interactive and dynamic user experiences. It allows web pages to send and receive data from a server without requiring a full page reload. In traditional web development, when a user interacts with a web page, the browser sends a request to the s...
Error Handling and Debugging
Error handling is essential for writing robust and reliable JavaScript code. It helps in detecting, handling, and recovering from errors that may occur during program execution. By implementing proper error handling techniques, we can prevent unexpected program crashes, improve the user experience, and make our code more maintainable. `javasc...
Introduction to ES6+
ES6+ refers to the newer versions of the ECMAScript standard, which is the specification that JavaScript is based on. ES6+ introduced several new features and syntax enhancements that have greatly improved the development experience and capabilities of JavaScript. One of the key features of ES6+ is the introduction of **b...
