I am trying to swap values of two variables using array destructuring, however I get the error Cannot access 'y' before initialization. Can someone please explain why it is not working and provide a solution

my code :

    let x = 'bob'
    let y = 'john'
    
    [x, y]=[y, x]
    
    console.log(x, y)

error: Cannot access 'y' before initialization

    Use semicolons. – Sebastian Simon Aug 25 '21 at 01:52

    Does this answer your question?

semicolons are missing

let x = 'bob';
let y = 'john';

[x, y]=[y, x];

console.log(x, y)
