Given an array of numbers, check if any of the numbers are the character codes for lower case vowels (a, e, i, o, u). If they are, change the array value to a string of that vowel. Return the resulting array. Solution: function isVow(a){ for (let index in a) { let vow = String.fromCharCode(a[index]) if (["a", "e", "i", "o", "u"].includes(vow)) { a[index] = vow } } return a } const isVow = a => a..

Write a method that takes one argument as name and then greets that name, capitalized and ends with an exclamation point. Example: "riley" --> "Hello Riley!" "JACK" --> "Hello Jack!" Solution: var greet = function(name) { modifiedName = name.charAt(0).toUpperCase() + name.slice(1).toLowerCase() return `Hello ${modifiedName}!` }; var greet = function(name) { return 'Hello ' + name[0].toUpperCase(..
