let a = 10; 
let b = 20;

let result = a > 0 && b > 10
console.log( result )      // true

// a > 0 is operand one    -------> The condition is true
// b > 10 is operand two   -------> The condition is true

// Here, The both conditions are same, So th AND Operator returns the true.

result = a < 0 && b > 0
console.log( result )     // fale

// a < 0 is first operand  -----> The condition is false.
// b > 0 is the second     -----> The condition is true.

// Here, The one condition is true, another one is false. So the AND Operator returns the false
