Loader
A loader is a software component or tool that loads data, code, or resources into memory or a system for execution or processing. It is commonly used in computing contexts such as operating systems, web development, and data pipelines to handle tasks like loading dynamic libraries, importing modules, or fetching external assets. Loaders ensure that dependencies are properly initialized and available for use by applications.
Developers should learn about loaders when building applications that require dynamic resource management, such as web apps needing to load JavaScript modules, operating systems handling executable files, or data systems importing datasets. They are essential for optimizing performance by enabling lazy loading, reducing initial load times, and managing dependencies efficiently in complex software projects.
