What are some useful functions in Lodash?

Lodash is a JavaScript utility library that provides helpful functions for common programming tasks. Some useful functions include _.map, _.filter, and _.debounce. Would you like to know more about any specific function?

Can you explain how _.map works?

Sure! _.map creates an array of values by running each element in a collection through a given iteratee function. For example, if you have an array of numbers and want to double them, you can use _.map to achieve that.

Can you show me a code example?

Absolutely! Here's a simple example:

const numbers = [1, 2, 3, 4];
const doubled = _.map(numbers, num => num * 2);
console.log(doubled); // Output: [2, 4, 6, 8]

What about _.filter?

_.filter creates an array of elements that pass a specified condition. For instance, if you want to filter out even numbers from an array, you can use _.filter to do that.
