Here’s another fun code challenge from Coderbyte:
Using the JavaScript language, have the function SimpleMode(arr) take the array of numbers stored in arr and return the number that appears most frequently (the mode). For example: if arr contains [10, 4, 5, 2, 4] the output should be 4. If there is more than one mode return the one that appeared in the array first (ie. [5, 10, 10, 6, 5] should return 5 because it appeared first). If there is no mode return -1. The array will not be empty.
This week’s JavaScript code challenge again comes from Coderbyte:
Using the JavaScript language, have the function Division(num1,num2) take both parameters being passed and return the Greatest Common Factor. That is, return the greatest number that evenly goes into both numbers with no remainder. For example: 12 and 16 both are divisible by 1, 2, and 4 so the output should be 4. The range for both parameters will be from 1 to 10^3.

Again, this week’s code challenge comes from my trusty favorite, Coderbyte:
Using the JavaScript language, have the function TripleDouble(num1,num2) take both parameters being passed, and return 1 if there is a straight triple of a number at any place in num1 and also a straight double of the same number in num2. For example: if num1 equals 451999277 and num2 equals 41177722899, then return 1 because in the first parameter you have the straight triple 999 and you have a straight double, 99, of the same number in the second parameter. If this isn’t the case, return 0.

This week’s code challenge comes again from Coderbyte:
Using the JavaScript language, have the function Consecutive(arr) take the array of integers stored in arr and return the minimum number of integers needed to make the contents of arr consecutive from the lowest number to the highest number. For example: If arr contains [4, 8, 6] then the output should be 2 because two numbers need to be added to the array (5 and 7) to make it a consecutive array of numbers from 4 to 8. Negative numbers may be entered as parameters and no array will have less than 2 elements.
