Array Exercises

Mild Practice

Calculate Daily Pay

Trisha gets paid $22 each time she walks a dog. The array below holds 7 numbers, the number of dog walks she took each day last week. Iterate over the array, and print out "Trisha earned $____ today!" for each day.

var dogWalks = [4, 5, 2, 2, 6, 1, 3]

YELLING

Iterate over an array of strings. For each string, print out the YELLING version of it. Look into how to convert a string to uppercase!

Medium Practice

Sum of All

Write a function that returns the sum of all of the numbers in an array. No empty arrays will be passed in. For example, when an array is passed like [19, 5, 42, 2, 77], the output should be 145.

Calculate Total Pay

Trisha gets paid $22 each time she walks a dog. The array below holds 7 numbers, the number of dog walks she took each day last week. Write a function that calculates her total pay.

var dogWalks = [4, 5, 2, 2, 6, 1, 3]

Spicy Practice

Sum of Two

Write a function that returns the sum of the two lowest positive numbers given an array of minimum 4 integers. No empty arrays will be passed in. For example, when an array is passed like [19, 5, 42, 2, 77], the output should be 7.

Find the Odd (or Even) One Out

Write a function that takes in one argument - an array of numbers. The array must have at least 3 elements. All numbers except for one of them will be either even or odd. You job is to return that one number that is the exception. Below are some example inputs and outputs. Make sure your function works on them all.

Input: [1, 3, 5, 6], Output: 6

Input: [10, 15, 20, 30, 40, 50], Output: 15

Input: [19, 5, 42, 1, 77], Output: 42
