Day 17: JavaScript Logic – Conditionals & Functions | 28-Day Web Developer Bootcamp

Welcome to Day 17 of the 28-Day Web Developer Bootcamp! 🚀 In today’s lesson, we are adding decision-making capabilities to our code with Conditionals and learning how to build reusable blocks of code using Functions . In this video, we cover: Making Decisions (Conditionals): Learn how to use if, else if, and else statements to allow your JavaScript to make decisions and execute different code based on varying conditions . Introducing Functions: Discover how to encapsulate repetitive tasks into reusable blocks . We will cover how to build your own functions, pass data into them using parameters, and output data using return values . Connecting Logic to the DOM: See how combining your new knowledge of functions and conditionals with event listeners (which we learned on Day 14) allows you to build powerful, interactive features—like toggling a page's dark mode or verifying user input before submission. 📅 About This Bootcamp: Have you ever wondered how websites are built? This complete, 28-day course takes you from writing your first line of code to understanding the core technologies of the modern web: HTML, CSS, and JavaScript. We believe that learning to code should be accessible to everyone. Inspired by initiatives like CodeYogi—which successfully teaches industry-standard programming to over 150,000 students entirely via smartphones using an AI chatbot and a Hindi-based curriculum —this course is designed so you can follow along whether you have a high-end laptop or are coding right from your mobile device. Initiatives like this show that you don't need expensive computers or classrooms to learn how to build the web; you just need curiosity, an internet signal, and a smartphone . In today’s lesson, we are diving into: [Brief 1-2 sentence description of what today's specific video covers. Example: "How to properly structure your HTML document and use the head tag for metadata."] 📅 About This Bootcamp: Have you ever wondered how websites are built?
