Lodash _.sample


Lodash is a popular JavaScript utility library that offers a lot of useful functions and methods to work with arrays, objects, strings, and more. One of the methods provided by Lodash is _.sample(), which allows you to retrieve a random element(s) from an array.

The syntax for using _.sample() is straightforward: _.sample(array, [n]). You provide an array to the method as the first argument, and an optional second argument, n, to specify how many random elements you want to retrieve from the array. If n is not provided, _.sample() returns a single random element.

Here is an example of using _.sample() with an array of numbers:

const numbers = [1, 2, 3, 4, 5];
const randomNumber = _.sample(numbers);
console.log(randomNumber); // could be any number between 1 and 5

In the above example, _.sample() returns a random element from the numbers array. It could be any number between 1 and 5.

You can also use _.sample() to retrieve multiple random elements from an array by passing in a second argument:

const numbers = [1, 2, 3, 4, 5];
const randomNumbers = _.sample(numbers, 3);
console.log(randomNumbers); // could be any three numbers from the array

In the above example, _.sample() returns an array of three random elements from the numbers array.

Keep in mind that _.sample() does not modify the original array in any way. It simply returns a new array with random elements.

Using _.sample() can be helpful in various scenarios, such as generating random content for testing or randomly selecting items for a game or lottery system.

In summary, _.sample() is a simple and useful method provided by Lodash to retrieve random elements from an array. It offers flexibility to retrieve a single random element or multiple random elements and can be helpful in various use cases.
