What is the most popular Web3 library?
Is Web3 js a library or Framework?
In the realm of web development, libraries and frameworks serve distinct purposes and play different roles. A library, by definition, is a compilation of pre-existing code that offers specific functionalities or features. Its purpose is to expedite the work of developers by providing readily available functions and APIs that can be seamlessly integrated into their projects. Libraries often address particular tasks or interactions within an application, offering a targeted solution.
On the contrary, a framework is a more comprehensive tool that provides a comprehensive structure and a predefined set of conventions for constructing applications. Typically, frameworks present a holistic solution, encompassing architectural patterns, libraries, and tools to streamline the development process. They often establish the overarching structure of an application and furnish guidelines for code organization and the management of various components.
