How to get the first n items in an array in JS
Given a JavaScript array, how do you get just the first X items of it?
Use the built-in slice()
method that comes with each array instance:
const arrayToCut = [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
const n = 5 //get the first 5 items
const newArray = arrayToCut.slice(0, n)
Note that the original array is not modified in this operation.
