assign multiple variables to the same value in Javascript

Question

I have initialized several variables in the global scope in a JavaScript file:

var moveUp, moveDown, moveLeft, moveRight;
var mouseDown, touchDown;
         


        

Answer 1

The original variables you listed can be declared and assigned to the same value in a short line of code using destructuring assignment. The keywords let, const, and var can all be used for this type of assignment.

let [moveUp, moveDown, moveLeft, moveRight, mouseDown, touchDown] = Array(6).fill(false);
