// 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) => {
    // ... write code ...
    let array = [];
    for(let i = 1; i <= length; i++){
        array.push(num * i);
    }
    console.log(array);
};
console.log("arrayOfMultiples");
arrayOfMultiples(7, 5);

// 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) => {
// ... write code ...
    console.log(array.reverse());
};
console.log("changeDirection");
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) => {
// ... write code ...
    let bigger;
    if(array1.length > array2.length){
        bigger = array1;
    }else{
        bigger = array2;
    }
    let res = 0;
    for(let i = 0; i < bigger.length; i++){
        res += bigger[i];
    }
    console.log({"array": bigger,"sum":res});

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