Using AI to write program code from a text description, from a single line up to a complete app.
Code generation means an AI model writes code instead of you or alongside you: a small function, a full page, or an app with its interface, server and database. Modern models know common languages and frameworks such as TypeScript, Python and React, and can explain and modify code as well.
The benefit is clear: faster and cheaper progress to a working version. But generated code can contain logic errors, security holes or unsuitable dependencies. Testing and review remain essential, as the guide to checking AI-generated code explains. Practical tip: make sure the code is yours and exportable to GitHub, and that every change is saved in version control. That way you can review what changed, undo any mistake and bring in a developer later if needed.
