Description: Method invocation is the process by which a method defined in an object is called in object-oriented programming languages such as Java, Python, and C#. This process allows executing a series of instructions encapsulated within the method, facilitating code modularity and reuse. Essentially, invoking a method involves accessing its functionality through its name, providing necessary arguments if required. Method invocation is fundamental for interacting with objects, as it allows manipulating their properties and performing specific actions. In languages like JavaScript, methods can be invoked directly on an object using dot or bracket notation. In languages such as Kotlin and TypeScript, method invocation follows a similar pattern but also incorporates additional features such as method overloading and type inference, enhancing code safety and readability. Method invocation is not only crucial for object-oriented programming but is also a central concept in functional programming, where functions can be treated as first-class objects.
