JavaScript Performance

Course overview

JavaScript Performance The JavaScript Performance course covers techniques for analyzing and optimizing the execution of JavaScript in web applications. Participants will learn how to measure runtimes, identify bottlenecks, and structure scripts to improve response times and resource usage. The course addresses measurement tools, efficient patterns, and the interaction of JavaScript with rendering and network processes. 1. Fundamentals - Performance and Measurement2. Efficient Script Structures3. DOM, Rendering, and Network4. Application and Optimization Processes 1. Fundamentals - Performance and Measurement Understanding the main thread, event loop, and task types Using browser profilers and timing tools Identifying bottlenecks in scripts and processes Differentiating between one-time and recurring costs 2. Efficient Script Structures Avoiding unnecessary calculations and multiple executions Using caching for reused results Structuring functions and modules to reduce coupling Handling asynchronous processes to relieve the main thread 3. DOM, Rendering, and Network Reducing frequent DOM changes and layout recalculations Utilizing batching and class changes instead of individual operations Being mindful of network calls and data volumes Employing simple strategies for script loading optimization 4. Application and Optimization Processes Step-by-step approach: Measure, Analyze, Adjust, Verify Documenting changes and their impacts Defining target values for response times and execution Preparing applications for increasing data volumes and usage scenarios
