I've been using this trick a few time now but I still can't wrap my head around why this works and can't seem to find the answer. Could anybody please explain ?
let myArray = [0, 1]
let [myVar] = myArray
console.log(myVar) // outputs 0
How is [myVar] the same thing as putting [0] behind myrArray ?
Edit: already asked and answered here : Multiple assignment in javascript? What does [a,b,c] = [1, 2, 3]; mean?
Thank you everyone
You are probably looking for this reference.
But basically, the brackets can be used to assign individual elements of a structure/array to variables, and it can be used with more than one, as well.
E.g.:
let myArray = [0, 1]
let [myVar1, myVar2] = myArray
console.log(myVar1) // outputs 0
console.log(myVar2) // outputs 1
PS: fyi these [] are square brackets, and these <> are angle brackets.
it is call "Destructuring_assignment" you can read more on that here
