Code snippets are small blocks of reusable code that can be easily integrated into larger programming projects. They help developers save time by providing pre-written solutions for common tasks, such as data manipulation or user interface elements. Code snippets can be found in various programming languages, including Python, JavaScript, and Java. These snippets can be shared among developers through online platforms or integrated into code editors, making it easier to collaborate and maintain consistency in coding practices. By using code snippets, programmers can focus on more complex aspects of their projects while ensuring that routine functions are handled efficiently.
