lodash.throttle is a standalone module offering the _.throttle function from the popular Lodash library. It limits the rate at which a function can be executed. Imagine you have a function that gets called repeatedly; throttle ensures it's only invoked at most once per specified duration. Effectively, it prevents over-frequent execution, enhancing performance, especially useful for handling events like resizing or scrolling. It's perfect for controlling potentially expensive operations triggered by user actions.
