Question

use JavaScript in Atom

Q1: create functions.js. You do not need to create a web page (.html) for this requirement. As you write each function, test it using the DevTools console. When it is correct, move on to the next function.

A) Write a function named isVowel that accepts a character and returns true if the character a vowel, false otherwise. Use a RegExp to solve this problem, and arrow function syntax.

Examples: > isVowel('Y')

> true

> isVowel('@')

> false

> isVowel('7')

> false

> isVowel('n')

> false

b) Write a function named daysInMonth that accepts a month number (1 .. 12) and returns the number of days in the month, leap years excluded. Use an array of length 12 to store the number of days in each month. Use arrow function syntax. Examples:

> daysInMonth(1)

> 31

> daysInMonth(2)

> 28

c) Write a function named daysInMonth_v2 that accepts a month number (1 .. 12) and a 4-digit year, and returns the number of days in the month, leap years included. Use an array of length 12 to store the number of days in each month. Use your isLeaper function from P3 to recognize leap years. Use arrow function syntax. Examples: > daysInMonth_v2(12, 2019)

> 30

> daysInMonth_v2(2, 2020)

> 29

d) Write a function named reverseWords that accepts a sentence of words separated by one space, and returns a sentence with each word reversed. reverseWords must call getWords and reverseString as part of the solution. See our class notes for how to reverse a string. Use arrow function syntax. Examples:

> reverseWords ('The quick brown fox')

> "ehT kciuq nworb xof"

> reverseWords ('abc defg')

> "cba gfed"

CODE

============

var isVowel = (char) => {
if (char.length == 1)
{
return /[aeiou]/.test(char);
}
}

var daysInMonth = (month) => {
let months = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31];

return months[month-1];
}
