Functions are one of the fundamental building blocks in JavaScript. It is a place where you can provide data for the function called and given when calling the function. Naming functions helps students write programs that read more like descriptions of what they do, and they also help students reuse code. A return value is a result of the function's execution. If you write code using object-oriented programming, you're going to find this principle of programming to be very useful.The composition over inheritance principle states: objects with complex behaviors should contain instances of objects with individual behaviors. Parameters are used to pass or assign values to an operation or routine at run time. Function parameters are the names listed in the function definition. Can a function can more than one parameter? As a strongly-typed language, C++ requires all variables to have a specific type, either explicitly declared by the programmer or deduced by the compiler.
