Code generation is the process of automatically creating source code from a higher-level representation, such as a model or a specification. This technique helps developers save time and reduce errors by automating repetitive coding tasks. Tools that facilitate code generation often use templates or predefined rules to produce code in various programming languages. In software development, code generation can be particularly useful in scenarios like model-driven development or when creating APIs. By generating code, developers can focus on designing features and functionality rather than writing boilerplate code, leading to more efficient and maintainable software projects.
