Generatorifunktioita

Generatorifunktioita, or generator functions in English, are a special type of function in programming that allows for the creation of iterators. These functions are defined using the "function*" syntax in JavaScript, and they use the "yield" keyword to produce a sequence of values over time, rather than computing them all at once and returning them in a list.

The primary advantage of generator functions is their ability to produce values on-the-fly and only when needed, which can lead to more efficient use of memory and computational resources. This is particularly useful when dealing with large datasets or infinite sequences.

Generator functions can be paused and resumed, making them useful for asynchronous programming and handling tasks that require waiting for some condition to be met before proceeding. They can also be used to implement custom iteration behavior for objects.

In summary, generator functions are a powerful tool in modern programming that provide a flexible and efficient way to work with sequences of values. They are supported in various programming languages, including JavaScript, Python, and others.
