What are some useful Lodash functions in JavaScript?

Lodash is a powerful utility library that provides many helpful functions. Some useful ones include _.map, _.filter, and _.debounce. Would you like to know more about any specific function?

Can you explain how _.debounce works?

Sure! _.debounce creates a debounced function that delays invoking the provided function until after a specified wait time has elapsed since the last time it was invoked. This is useful for limiting the rate at which a function can fire, such as during window resizing or keypress events.

How do I use _.map with an array?

You can use _.map to iterate over an array and transform its elements. For example: _.map([1, 2, 3], n => n * 2) will return [2, 4, 6].

Are there any performance considerations when using Lodash?

Yes, while Lodash is optimized for performance, using it excessively or in tight loops can lead to overhead. It's best to use it judiciously.
