How to empty a JavaScript array
New Course Coming Soon:
Get Really Good at Git
Given a JavaScript array, see how to clear it and empty all its elements
There are various ways to empty a JavaScript array.
The easiest one is to set its length to 0:
const list = ['a', 'b', 'c']
list.length = 0
Another method mutates the original array reference, assigning an empty array to the original variable, so it requires using let
instead of const
:
let list = ['a', 'b', 'c']
list = []
Are you intimidated by Git? Can’t figure out merge vs
rebase? Are you afraid of screwing up something any time

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 May 21, 2024. Join the waiting list!
