The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - What Are Libraries in Solidity

The video tutorial explains the concept of libraries in Solidity, highlighting their similarities to contracts and their primary purpose of reusability. It covers the key characteristics and restrictions of libraries, such as being stateless and not supporting inheritance. The tutorial then demonstrates how to create a library with a search function, using loops and conditional statements. It concludes with testing the library by deploying a contract and running tests to verify the functionality of the search function.

What is the process to search for a value in an array using a library function?

Discuss the importance of the constructor in the context of a contract using a library.

What happens when a library is called from a contract?

What is the expected output when searching for a value that exists in the array?
