JavaScript Coding Question – 3

let x = 5;
let y = 7;
let z = 1;

let result = x + y;
result += x;
result -=z;

console.log(result);

Output:

16

• result = x + y : 5 + 7 = 12;
• result += x : Which is equal to result = result + x, means 12 + 5 = 17.
• result -=z : Which is equal to result = result – z, means 17 – 1 = 16.
