\title Advanced QML Topics
\brief Advanced features and optimization techniques for QML
 
This section covers advanced topics for optimizing and fine-tuning QML applications.
 
\section1 Caching and Performance
 
\section2 The QML Disk Cache
 
\l{The QML disk cache}{The QML disk cache} stores compiled QML and JavaScript code on disk
to improve application startup time. When a QML document is loaded for the first time, it's
compiled to bytecode and cached in a platform-specific location. Subsequent loads of the
same document can use the cached bytecode instead of recompiling from source, significantly
reducing initialization overhead.
 
\section1 JavaScript Engine Configuration
 
\section2 Configuring the JavaScript Engine
 
\l{Configuring the JavaScript engine}{The JavaScript engine can be configured} with various
environment variables to control compilation behavior, garbage collection settings, and
runtime optimizations. These settings allow you to tune the JavaScript engine for specific
use cases, such as favoring startup time over peak performance or adjusting memory usage
patterns.
 
\section2 Memory Management in the JavaScript Engine
 
\l{Memory Management in the JavaScript Engine}{The JavaScript engine uses garbage collection}
to automatically reclaim memory from objects that are no longer in use. Understanding how
the garbage collector works, including generational collection strategies and heap organization,
helps you write QML and JavaScript code that performs efficiently and avoids common memory-related
performance pitfalls.
