Then, you can import the initial function from lodash and use it to get all but the last element of an array:

index.ts
import { initial } from 'lodash';

const myArray = [1, 2, 3, 4, 5];
const allButLast = initial(myArray);

console.log(allButLast); // [1, 2, 3, 4]

7 lines

The initial function takes an array as its first argument and returns a new array with all but the last element. Note that initial does not modify the original array, but returns a new one. Also, if the original array is empty or has only one element, initial will return an empty array.
