                return Math.floor(Math.random() * 101)
            }

        Code for its execution:
        
          const result = randomNumber()

Exercise 3

        Function declaration:
        
          class Person {
            constructor(name) {
              this.name = name

          const printNumbers = (numbersArray = []) => {
            for (let i = 0; i < numbersArray.length - 1; i++) {
              console.log(numbersArray[i])
            }
          }

        Code for its execution:
        
          const numbers = [1, 2, 3, 4, 5]
          printNumbers(numbers)
