Yield (in Programming)
In programming languages like Python and JavaScript, yield is a keyword used within a function to pause its execution and return a value to the caller, while maintaining the function’s state for subsequent resumption. Functions that use yield are known as generator functions. They generate a sequence of values over time, producing items one at a time only when required (lazy evaluation). This approach is memory-efficient, especially when working with large datasets or streams, as it doesn’t require storing the entire dataset in memory.
