Examples dashed("Carpe Diem") ➞ "C-a-rp-e- D-i--e-m" dashed("Fight for your right to party!") ➞ "F-i-ght f-o-r y-o--u-r r-i-ght t-o- p-a-rty!" Notes
There are already a couple of solutions using regex; therefore, I am adding an answer which can be useful to someone who is not familiar with regex.
The following function, referenced by formatVowels, iterates the parameter string and uses String#indexOf to check if any of the characters is a vowel; if yes, it prepends and appends - to it and then adds the resulting text to the variable, result, otherwise, adds the character as it is to the variable, result.
const formatVowels = (str) => {
if (str == undefined) return "";
let result = "";
for (const ch of str) {
result += "AEIOU".indexOf(ch.toUpperCase()) != -1 ? "-" + ch + "-" : ch;
}
return result;
};
// Test
console.log(formatVowels('Hello'));coolString = `Cookke`;
function dashed(coolString) {
const regex = /a|e|i|o|u/gi;
console.log(coolString.replace(regex, `-$&-`));
}
dashed(coolString);const my_replacer = (str)=> str.replace(/[aeiouAEIOU]/g,'-$&-')
let a = 'Carpe Diem'
console.log(my_replacer(a))
let b = 'Fight for your right to party!'
console.log(my_replacer(b))
