// 1 =================================
// Create a function that takes two numbers as arguments (num, length) and returns an array of multiples of num until the array length reaches length.
// Examples
// arrayOfMultiples(7, 5) ➞ [7, 14, 21, 28, 35]
// arrayOfMultiples(12, 10) ➞ [12, 24, 36, 48, 60, 72, 84, 96, 108, 120]
// arrayOfMultiples(17, 6) ➞ [17, 34, 51, 68, 85, 102]

// Your code:
const arrayOfMultiples = (num, length) => {
    let array = []
    for (let i = 1; i <= length;i++){
        array.push(num * i)
    }
    return array
};
console.log(arrayOfMultiples(1.8, 9))
// 2 =================================
// Change direction of array
// TIP: Check if there is function which can help you https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array
// Example:
// changeDirection([0, 1, 2, 3]) ➞ [3, 2, 1, 0]
// changeDirection([]) ➞ []
// changeDirection([1, 2]) ➞ [2, 1]

// Your code:
const changeDirection = (array) => {
    let reverse = []
    for (let i = array.length - 1; i >= 0; i--){
        reverse.push(array[i])
    }
    return reverse
};
console.log(changeDirection([0, 1, 2, 3]))
// 3 =================================
// Create function that takes two arrays and return object with two keys - bigger array, sum all numbers
// Examples
// biggerArray([1,2,3,4,5], [50,50]) ➞ { array: [50,50], sum: 100 }
// biggerArray([1,2,3], [2,3,4]) ➞ { array: [2,3,4], sum: 9 }

// Your code:
const biggerArray = (array1, array2) => {

    let sum1 = 0
    let sum2 = 0
    let length = array1.length > array2.length ? array1.length : array2.length

    for(let i = 0; i < length;i++){
        if(i < array1.length) sum1 += array1[i]
        if(i < array2.length) sum2 += array2[i]
    }
    function Result(array, sum) {
        this.array = array
        this.sum = sum
    }
    return sum1 > sum2 ? new Result(array1, sum1) : new Result(array2, sum2)

};
console.log(biggerArray([1,2,3,4,5], [50,50]))
console.log(biggerArray([1,2,3], [2,3,4]))
