Description: A function library is a collection of functions that can be used in programming. These libraries allow developers to reuse code, making it easier to implement common functionalities without having to write them from scratch. Libraries can be written in various programming languages and typically group related functions that serve a specific purpose, such as string manipulation, mathematical operations, and database access, among others. By using a function library, programmers can save time and effort, improve code readability, and reduce the likelihood of errors, as the functions in these libraries are often well-tested and documented. Function libraries are essential for creating plugins and extensions that enhance the capabilities of various software applications. In languages like PHP and TypeScript, these libraries are fundamental for web application development, allowing developers to implement complex features efficiently and effectively.
