Duration 5 days – 35 hrs
Overview
This comprehensive training course introduces participants to JavaScript, the core programming language of the web. It covers everything from basic syntax and DOM manipulation to asynchronous programming and modern ES6+ features.
Through hands-on exercises and real-world examples, participants will learn to create dynamic, interactive, and user-friendly web applications using JavaScript and related web technologies.
Objectives
- Understand the fundamental concepts and syntax of JavaScript.
- Manipulate HTML and CSS dynamically through the Document Object Model (DOM).
- Implement interactive web features and handle user input events.
- Apply ES6+ modern JavaScript features for cleaner and more efficient code.
- Work with APIs and asynchronous operations using Promises and async/await.
- Debug, test, and optimize JavaScript code for web applications.
- Develop a simple front-end application integrating HTML, CSS, and JavaScript.
Audience
- Beginners aspiring to become web developers.
- Front-end designers looking to enhance interactivity skills.
- Developers transitioning from other programming languages.
- Students and professionals wanting to understand client-side scripting.
Prerequisites
- Basic knowledge of HTML and CSS.
- Familiarity with general programming concepts (variables, functions, logic) is helpful but not required.
