Synchronous Calls
Synchronous calls are a programming paradigm where operations are executed sequentially, blocking further execution until the current operation completes. This means the program waits for a function or method to return a result before proceeding to the next line of code. It is a fundamental concept in software development, often contrasted with asynchronous programming for handling tasks like I/O operations or network requests.
Developers should use synchronous calls for simple, linear tasks where order of execution is critical and blocking is acceptable, such as mathematical calculations or file reading in small applications. It is essential to learn this concept to understand basic program flow and as a foundation for grasping more complex asynchronous patterns, which are crucial in modern web and mobile development for performance optimization.
