Objectives Get comfortable with loops: for and while. Get comfortable with conditionals: if/else.
Always Hungry Write a function that is given an array and each time the value is "food" it should console log "yummy". If "food" was not present in the array console log "I'm hungry" once. function alwaysHungry(arr) { // your code here }
alwaysHungry([3.14, "food", "pie", true, "food"]); // this should console log "yummy", "yummy" alwaysHungry([4, 1, 5, 7, 2]); // this should console log "I'm hungry"copy High Pass Filter Given an array and a value cutoff, return a new array containing only the values larger than cutoff. function highPass(arr, cutoff) { var filteredArr = []; // your code here return filteredArr; } var result = highPass([6, 8, 3, 10, -2, 5, 9], 5); console.log(result); // we expect back [6, 8, 10, 9]copy Better than average Given an array of numbers return a count of how many of the numbers are larger than the average. function betterThanAverage(arr) { var sum = 0; // calculate the average var count = 0 // count how many values are greated than the average return count; } var result = betterThanAverage([6, 8, 3, 10, -2, 5, 9]); console.log(result); // we expect back 4copy Array Reverse Write a function that will reverse the values an array and return them. function reverse(arr) { // your code here return arr; }
var result = reverse(["a", "b", "c", "d", "e"]); console.log(result); // we expect back ["e", "d", "c", "b", "a"]copy Fibonacci Array Fibonacci numbers have been studied for years and appear often in nature. Write a function that will return an array of Fibonacci numbers up to a given length n. Fibonacci numbers are calculated by adding the last two values in the sequence together. So if the 4th value is 2 and the 5th value is 3 then the next value in the sequence is 5.
