Array destructuring JS
// In an array destructuring from an array of length N specified on the right-hand side of the assignment, if the number of variables specified on the left-hand side of the assignment is greater than N, only the first N variables are assigned values. The values of the remaining variables will be undefined. const foo = ['one', 'two']; const [red, yellow, green, blue] = foo; console.log(red); // "one" console.log(yellow); // "two" console.log(green); // undefined console.log(blue); //undefined
