The logical operators (&&, ||, and !) can be used in combination with the if-else statement to create more complex conditions and control the flow of execution in a program. Here's an example of using the && operator to evaluate multiple conditions in an if-else statement:

let score = 75;
let grade;
 
if (score >= 90 && score <= 100) {
  grade = 'A';
} else if (score >= 80 && score < 90) {
  grade = 'B';
} else if (score >= 70 && score < 80) {
  grade = 'C';
} else {
  grade = 'F';
}
 
console.log('Your grade is ' + grade);

In this example, the && operator is used to evaluate two conditions for each of the if statements. If both conditions are true, then the corresponding code block will be executed and the value of grade will be assigned. In this case, since score is equal to 75, the conditions for A and B are not met, and the condition for C is met, so the value of grade is assigned to "C". Here's an example of using the || operator:

let age = 15;
let canDrive;
 
if (age >= 16 || age >= 18) {
  canDrive = true;
} else {
  canDrive = false;
}
 
console.log('Can you drive? ' + canDrive);

In this example, the || operator is used to evaluate two conditions in the if statement. If either condition is true, then the code block will be executed and the value of canDrive will be assigned to true. In this case, since age is equal to 15, neither condition is met, so the value of canDrive is assigned to false. The ! operator can be used to negate a condition and reverse its value. For example:

let isSunny = false;
let bringUmbrella;
 
if (!isSunny) {
  bringUmbrella = true;
} else {
  bringUmbrella = false;
}
 
console.log('Bring an umbrella? ' + bringUmbrella);

In this example, the ! operator is used to negate the value of isSunny, which is false. The result is that the condition in the if statement is true, and the value of bringUmbrella is assigned to true.
