Function Problems With Scope

1

Write a function printCool that accepts one parameter, name as an argument. The function should print the name and a message saying that that person is cool.

console.log(printCool("Captain Reynolds"));

=> "Captain Reynolds is cool";

2

Write a function calculateCube that takes a single number and prints the volume of a cube made from that number.

console.log(calculateCube(5));

=> 125

3

Write a function isAVowel that takes a character (i.e. a string of length 1) and returns true if it is a vowel, false otherwise. The vowel could be upper or lower case.

console.log(isAVowel("a"));

=> true

4

Write a function getTwoLengths that accepts two parameters (strings). The function should return an array of numbers where each number is the length of the corresponding string.

console.log(getTwoLengths("Hank", "Hippopopalous"));

=> [4, 13]

5

Write a function getMultipleLengths that accepts a single parameter as an argument: an array of strings. The function should return an array of numbers where each number is the length of the corresponding string.

console.log(getMultipleLengths(["hello", "what", "is", "up", "dude"]));

=> [5, 4, 2, 2, 4]

6

Define a function maxOfThree that takes three numbers as arguments and returns the largest of them. If all numbers are the same, it doesn't matter which one is returned. If the two largest numbers are the same, one of them should be returned.

console.log(maxOfThree(6, 9, 1));

=> 9

7

Write a function printLongestWord that accepts a single argument, an array of strings. The method should return the longest word in the array. In case of a tie, the method should return the word that appears first in the array.

console.log(printLongestWord(["BoJack", "Princess", "Diane", "a", "Max", "Peanutbutter", "big", "Todd"]));

=> "Peanutbutter"

8

Write a Javascript function called transmogrify. This function should accept three arguments, which you can assume will be numbers. Your function should return the "transmogrified" result.

The transmogrified result of three numbers is the product of the first two numbers, raised to the power of the third number.

For example, the transmogrified result of 5, 3, and 2 is (5 times 3) to the power of 2 is 225.

console.log(transmogrify(5, 3, 2));

=> 225

Project Euler problem #2

• Write a function that takes a parameter, a number. The function should print the Fibonacci sequence up to that number.

• Adjust the function to push the even numbered values into an array.

• Adjust the function to return the summed value of the array.

• Find the sum of the even numbered values that do not exceed four million.
