HackerRank 10 Days of Javascript: Day 2: loops

Task:

Complete the vowelsAndConsonants function in the editor below. It has one parameter, a string, , consisting of lowercase English alphabetic letters (i.e., a through z). The function must do the following:

1. First, print each vowel in on a new line. The English vowels are a, e, i, o, and u, and each vowel must be printed in the same order as it appeared in .
2. Second, print each consonant (i.e., non-vowel) in on a new line in the same order as it appeared in .

Sample Input:

Sample Output:

a
a
i
o
o
j
v
s
c
r
p
t
l
p
s

My Code:

• I am using Regex to remove the vowels and consonants from the string.
• regex = /[aeiou]/gi is used to remove all the vowels from the string.
• In the regex above i is a flag that means ‘ignore’, I used this to avoid the lowercase and uppercase problems.
• regex = /[^aeiou]/gi is used to remove all the consonants from the string.
• ^ means negating the character set.

function vowelsAndConsonants(s) {
let str = '';
var v = s.replace(/[^aeiou]/gi, '');
str += v;
var c = s.replace(/[aeiou]/gi, '');
str += c;
for (var i of str) {
console.log(i);
}
}

We can optimize this code :

function vowelsAndConsonants(s) {
let str = s.replace(/[^aeiou]/gi, '') + s.replace(/[aeiou]/gi, '');
for (var i of str) {console.log(i);}
}
