JavaScript Arithmetic with Boolean Values

the JavaScript code console.log((true + true) * (true + true) - true * true); uses boolean values in arithmetic operations. In JavaScript, true is treated as 1 for these operations. Let's break down the code step by step:

1. First part: (true + true)
   • true is treated as 1, so true + true is 1 + 1, which equals 2.
2. Second part: (true + true) * (true + true)
   • we just fond that true + true is 2. So, this becomes 2 * 2, which equals 4.
3. Third part: true * true
   • Again, true is 1, so true * true is 1 * 1, which equals 1.
4. final calculation: 4 - 1
   • Subtracting 1 from 4 gives 3.

so the output of the code is 3.

this happens because in JavaScript, true behaves like 1 when you use it in mathematical operations.
