Yield Keyword

The yield keyword is used in programming languages such as Python and JavaScript to produce values from a function without completing the function's execution. When execution reaches yield, the current state is preserved so the function can continue from the same point when the next value is requested.

Yield is commonly used to create generators, which process or produce data lazily instead of loading every value into memory at once. This can make iteration more memory-efficient when working with large datasets, streams, sequences, or other values that can be generated on demand.
