Description: The ‘defer’ in Golang is a statement that postpones the execution of a function until the surrounding function returns. This feature allows developers to manage the execution of cleanup or resource release functions more efficiently and readably. By using ‘defer’, one can ensure that certain actions, such as closing files or releasing database connections, are performed regardless of how one exits the function, whether through a normal return or an error. ‘Defer’ statements are executed in the reverse order of their declaration, providing additional control over the execution flow. This functionality not only improves code readability but also reduces the likelihood of errors by ensuring that cleanup tasks are performed predictably. In summary, ‘defer’ is a powerful tool in Golang that enables developers to write cleaner and safer code, facilitating resource management and controlled function execution.
