Desafío final - Seccion 4

Holaa ;) vuelvo a dejar mi codigo como referencias!

// 1. Show a welcome message
console.log(`Welcome user! :)`);

// 2. Log a message with a name variable
const userName = `Kevin`;
console.log(`Hi, ${userName}!`);

// 3. Alert the same message
alert(`Hi, ${userName}!`);

// 4. Ask a question and logs
const userAnswer = prompt(`What's your favorite programming language?`);
console.log(userAnswer);

// 5. Add two values
let value1 = 15;
let value2 = 25;
let result = value1 + value2; // 15 + 25 = 40

console.log(`The sum of ${value1} plus ${value2} is equals to ${result}`);

// 6. Subtract two values
value1 = 10;
value2 = 2;
result = value1 - value2; // 10 - 2 = 8

console.log(
  `The subtraction of ${value1} minus ${value2} is equals to ${result}`
);

// 7. Check 18 years old
const userAge = +prompt(`Type your age: `);

if (userAge >= 18) {
  console.log(`You are an adult!`);
} else {
  console.log(`You are still young!`);
}

// 8. Check if it's positive o negative number
const num = +prompt(`Type a number: `);

if (num === 0) {
  console.log(`It's zero! (0)`);
} else {
  if (num > 0) {
    console.log(`It's a positive number! (${num})`);
  } else {
    console.log(`It's a negative number! (${num})`);
  }
}

// 9. Show 1 - 10 using while loop
let count = 1;

// * One way
while (true) {
  console.log(count++);

  if (count > 10) {
    break;
  }
}

// * Other way
count = 1;

while (count <= 10) {
  console.log(count++);
}

// 10. Grades check
const grade = 9;

if (grade >= 7) {
  console.log(`Passed!`);
} else {
  console.log(`Failed!`);
}

// 11, 12 & 13 - Math.random
// 11
console.log(Math.random());

// 12
console.log(Math.floor(Math.random() * 10) + 1);

// 13
console.log(Math.floor(Math.random() * 1000) + 1);
