How to Jump Values in The Array Destructuring

To skip a value when using the array destructuring assignment syntax we just leave it blank and put a comma after it.

Here is an example of destructuring out the second and third values of an array.

const [,b,c] = [1, 2, 3, 4, 5];
console.log(b);
//2
console.log(c);
//3

Below is an example of extracting out only the third value of the array.

const [,,c] = ['A', 'B', 'C'];
console.log(c);
//'C'

Here is an example of destructuring out the third value from a comma-separated string. We first split the CSV string by comma and use the destructuring assignment syntax to extract the third value from the returned array.

const csvText = '1,Overwatch,Blizzard';
const [,,developer] = csvText.split(',');
console.log(developer);
//'Blizzard'
