Day 5: Arrow Functions

    For better understanding .. every new method is a modification of previous method.. This is how it helped me understand the arrow function.

    //method 1

    function modifyArray(nums) {
    var something = function(n){
        if(n%2==0)
            return n*2;
        else
            return n*3;
    }
    var newArray = nums.map(something);
    return newArray;
    
}

    // method 2

    function modifyArray(nums) {
    var something = function(n){
        var a = (n%2==0) ? n*2: n*3;
        return a;
    }
    var newArray = nums.map(something);
    return newArray;
    
}

    //method 3

    function modifyArray(nums) {
    var something = n => n = (n%2==0) ? n*2: n*3;
    var newArray = nums.map(something);
    return newArray;
    
}

    //method 4

    function modifyArray(nums) {
    var newArray = nums.map(n => n = (n%2==0) ? n*2: n*3);
    return newArray;
    
}

    //method 5

    function modifyArray(nums) {
    return nums.map(n => n = (n%2==0) ? n*2: n*3);   
}
