How to get the first n items in an array in JS
New Course Coming Soon:
Get Really Good at Git
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.
Are you intimidated by Git? Can’t figure out merge vs
rebase? Are you afraid of screwing up something any time
you have to do something in Git? Do you rely on ChatGPT
or random people’s answer on StackOverflow to fix your
problems? Your coworkers are tired of explaining Git to
you all the time? Git is something we all need to use,
but few of us really master it. I created this course to
improve your Git (and GitHub) knowledge at a radical
level. A course that helps you feel less frustrated with
Git. Launching Summer 2024. Join the waiting list!
