Design a function that accepts a string parameter and outputs an encoded (h4ck3r 5p34k) rendition of the input string

 function convertToHacker(str){
    for (var i=0; i <str.length;i++)
      {
    if (str[i]==="a")
       {str=str.replace("a","4")}
    else if (str[i]==="e")
        {str=str.replace("e","3")}
    else if (str[i]==="i") 

     {str=str.replace("i","1")}
    else if (str[i]==="o")
          {str=str.replace("o","0")}
    else if (str[i]==="s")
          {str=str.replace("s","5")}
    else {}
        }
    return str
  }

  document.write (convertToHacker("become a coder"))

The output is not as expected and upon checking the code, it seems there are issues with comparison operators ('=' instead of '=='). The function should replace all 'a's with 4, 'e's with 3, 'i's with 1, 'o's with 0, and 's's with 5.

String#replace function does not alter the original string (it is non-mutating), rather it creates and returns a new one.

My recommendation would be to continue using the replace function but also experiment with regular expressions :)

const dictionary = {
   a: 4,
   e: 3,
   i: 1,
   o: 0,
   s: 5,
};

function hackerSpeak(str) {
  return str.replace(/[aeios]/gi, (m) => dictionary[m]); 
  // this will produce a modified version of the string
}

document.write(hackerSpeak("become a coder"))

function convertToHackerSpeak(statement) {
    const leet = {'a': 4, 'b': 3, 'i': 1, 'o': 0, 's': 5}
    const speak = letter => leet.hasOwnProperty(letter) ? leet[letter] : letter

    return statement.split('').map(speak).join('')
}

console.log(convertToHackerSpeak("I am learning to code like a pro"));

    const leet = {'a': 4, 'b': 3, 'i': 1, 'o': 0, 's': 5}
    const speak = letter => leet.hasOwnProperty(letter) ? leet[letter] : letter

    return statement.split('').map(speak).join('')
}

console.log(convertToHackerSpeak("I am learning to code like a pro"));

Let's clarify something: In JavaScript, a single "=" is not a comparison operator; it is used for value assignment. To compare two values, use "==" or "===".

For string comparison, it is recommended to use the ".equals(...)" method.
