Linq has a convenient operator method called Take() to return a given number of elements in anything that implements IEnumerable. Is there anything similar in jQuery for working with arrays?

Or, asked differently: how can I truncate an array in Javascript?

There is a slice method

let arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

arr = arr.slice(0, 4);

console.log(arr);

Will return the first four elements.

Don't forget to assign it back to your variable if you want to discard the other values.

Note: This is just regular javascript, no need for jquery.
