Namespaces
Namespaces are a programming concept used to organize code by grouping related identifiers (such as variables, functions, or classes) under a unique name to prevent naming conflicts. They provide a way to encapsulate code elements, making large codebases more manageable and modular. This concept is widely implemented in languages like C++, Python, and PHP to avoid collisions between identifiers from different libraries or modules.
Developers should learn and use namespaces when working on large-scale projects or integrating multiple libraries to avoid identifier clashes, which can cause bugs and maintenance issues. They are essential in object-oriented and modular programming to improve code readability, organization, and reusability, particularly in team environments where code from different sources is combined.
