By Using Replace And Regex: I Have Captured C, But I Want To Set It At The End Of Osonant Plus “ay” With Replace In Javascript

Here is he link: https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/intermediate-algorithm-scripting/pig-latin. By using replace and regex: I have capture

Solution 1:

See if that's what you want

function translatePigLatin(str) {   
  let regx = /(.*?)([^aeiou])(.*)/i
  console.log(str.replace(regx, '$1$3ay$2'))
} 
  
translatePigLatin("consonant")

// output onsonantayc

Your question is a bit vague, if not add more information in the comments

Solution 2:

Pig Latin is a way of altering English Words. The rules are as follows:

• If a word begins with a consonant, take the first consonant or consonant cluster, move it to the end of the word, and add "ay" to it.

• If a word begins with a vowel, just add "way" at the end.

A possible solution:

function translatePigLatin(str) {
    if (!/[aeiou]/.test(str)) { // if it does not contain vowels
        return str + "ay";
    } else if (/^[aeiou]/.test(str)) { // if it starts with a vowel
        return str + "way";
    } else { // if it starts with a consonant and has vowels
        let regx = /(.*?)([aeiou])(.*)/i;
        return str.replace(regx, "$2$3$1ay");
    }
}

console.log(translatePigLatin("pig")); // igpay
console.log(translatePigLatin("rythm")); // rythmay
console.log(translatePigLatin("consonant")); // onsonantcay

The regular expression /(.*?)([aeiou])(.*)/i means:

(.*?) match as minimum characters as possible

([aeiou]) followed by a vowel and

(.*) followed by the rest of the string.

By usinig the parenthesis, we are creating backreferences $1, $2, $3 that will store each of these values for later use with the replace method.
