The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - How Does Require Work in Solidity

The video tutorial explains error handling in programming using a sunny weather example. It introduces a boolean variable to check weather conditions and a function to perform solar calculations. The tutorial demonstrates using the 'require' statement to ensure conditions are met before executing functions. It also includes a fun example of a weather control function that toggles weather conditions. The tutorial concludes with testing the functions and handling errors through reversion, providing a practical understanding of error handling in programming.
