I would like to replace string characters-CodePudding

Hello Please Im trying to reverse a string using the following:

Receive a character string as a parameter.
Replace the vowels with the letter “V”.
Reverse the string.
Return the result

And this is my code, but it does not seem to work, so I need some help please. Thanks

function reverseString(str) {
    let charactere = str.split("").replace(/(a)|(i)|(e)/g, ‘V’);
    charactere.reverse().join(" ");

    return str;
}

CodePudding user response：

You should perform the replace first, because it must be performed on a String. split() returns an Array, and an Array does not have a replace() method.

Finally, if you return str, you are only returning the original input of the function. Here I save the result of reversing charactere to a new variable (revStr) and return it instead.

function reverseString(str) {
    let charactere = str.replace(/(a)|(i)|(e)/g, 'V').split("");
    const revStr = charactere.reverse().join("");
    return revStr;
}

console.log(reverseString('abcdefg')) // 'gfVdcbV'

Just replace -> split -> reverse -> join

var x = "1addiiidfa"
var res = x.replace(/[aie] /g,"V").split('').reverse().join('')
console.log(res)
