Core And Essential Javascript Knowledge

JavaScript for beginners and Intermediates

What you'll learn

Confidently use variables (var, let, const), operators, and control flow (if/else, switch) to build basic programs.

Manipulate arrays (add/remove elements, search) and objects (properties, methods), and write reusable code with functions/arrow functions.

Select and modify webpage elements by ID, class, or tag name, and respond to user interactions (clicks, inputs) using event listeners.

Apply loops, scope rules, and built-in objects (String, Math, Date) to complete exercises like checking vowels or iterating through 2D arrays.

Requirements

Basic HTML and CSS knowledge

Description

This course offers a comprehensive introduction to JavaScript, covering fundamental concepts like variables (var, let, const), arithmetic operators, and concatenation. It progresses to control structures such as switch-case, if-else statements, and loops (for, while, do…while). Students will also explore arrays, including searching, checking, and iterating through them using various methods. The curriculum ensures a solid foundation in JavaScript syntax and logic, preparing learners for more advanced topics.The course delves into JavaScript objects, classes, and functions, including arrow functions and parameter handling. It introduces the String, Date, and Math objects, along with DOM manipulation techniques like selecting elements by ID, class, or tag name. Events, pop-up boxes, and library operators are also covered. These modules equip students with the skills to create dynamic, interactive web applications, emphasizing practical exercises and real-world applications.Advanced topics include 2D arrays, scope (local and global), and JavaScript’s parent-child-sibling relationships in the DOM. The course also covers query selection, innerText, innerHTML, and textContent for dynamic content updates. By the end, learners will have a thorough understanding of JavaScript’s core features and its role in web development, enabling them to build robust, efficient, and user-friendly applications. The structured approach ensures gradual progression from basics to advanced concepts.
