How to destructure an object to an already defined variable
New Course Coming Soon:
Get Really Good at Git
I had the need to assign the result of a function call to a variable already defined. The function returned an object:
function test() {
return {
one: 1,
two: 2
}
}
I thought I’ll just use object destructing, like this:
const { one, two } = test()
But I had two
already defined in my code (because of scoping issues) and I couldn’t redeclare it:
let two
//...
const { one, two } = test() //ERROR
Simple way would be to have
const result = test()
two = result.two
const { one } = result
Or, I could also declare one
as let
and use this syntax with parentheses (adding ;
before them to prevent JS to freak out because I don’t use semicolons, any line starting with (
must start with a semicolon, simple rule)
let one, two
;({ one, two } = test())
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!
