Important: You shouldn't use global variables

1) Write largest and smallest functions that returns the largest and smallest number passed like a argument.

Example:

largest(2, 0.1, -5, 100, 3) // 100
smallest(2, 0.1, -5, 100, 3) // -5

2) Write function transform that will transform array of numbers to array of functions that will return value from a base array.

Example:

const baseArray = [10, 20, 30, 40, 50];
const newArray = transform(baseArray);
newArray[3](); // should return 40
newArray[4](); // should return 50

3) Write function sum. Function expects arbitrary number of digit arguments and returns compound value of them.

Note: function should use recursion

Example:

sum(1,3,5,7); //should return 16

4) Write function countDown. Function expects number and logs values one by one till zero with one second delay.

Example:

countDown(3); // 3 2 1 0

5) Write a polyfill for a .bind() function and save it in Function.prototype.myBind(). myBind() should work in an exact same way as the usual bind() - take context as a first parameter and the list of arguments separated by comma.

Hint: play with the function in Function.prototype and see what this points to inside it. Your code should look like: Function.prototype.myBind = function () {
// your code here
}

Example:

function addPropToNumber(number) { return this.prop + number; }
var bound = addPropToNumber.myBind({ prop: 9 });
bound(1) // 10
