Web Performance and Memory Optimization with DevTools

Slow loading times and unresponsive interfaces frustrate users and hurt search rankings, yet diagnosing these performance bottlenecks can feel like searching for a needle in a haystack. Unseen memory leaks and inefficient JavaScript execution often degrade application performance without throwing a single error. This written course equips you with the fundamental knowledge and practical strategies needed to identify, diagnose, and resolve web performance issues. You will transition from guessing why an application is slow to systematically analyzing and fixing performance bottlenecks in any codebase. What you'll learn: - Understand the core metrics of web performance, including Core Web Vitals and rendering lifecycles - Analyze runtime performance and CPU bottlenecks using Chrome DevTools - Identify and resolve memory leaks and logical flaws in JavaScript code - Apply code-splitting and modern loading patterns to improve initial load times - Optimize resource utilization to ensure smooth experiences across diverse user devices You will begin by learning the foundational terminology of browser rendering and performance metrics before moving into step-by-step written guides on navigating profiling tools. Through clear text explanations and code analysis exercises, you will practice detecting memory leaks and refactoring inefficient code patterns. This course is designed for web developers and beginners eager to write faster, more efficient code, requiring only a basic understanding of HTML, CSS, and JavaScript.
