How to translate the function

Write a function translate() that will translate a text into "rövarspråket". That is, double every consonant and place an occurrence of "o" in between. For example, translate("this is fun") should return the string "tothohisos isos fofunon"

Simple regex replacement - but you need to decide for yourself whether you want to treat Y as a vowel or as a consonant:

function translate(text, cons, char) {
    // translate text into "rövarspråket"
    // text - string
    // cons (optional) - regex with character list to be replaced, must have 1 group
    // char (optional) - character to insert between duplicated cons
    cons = cons || /([bcdfghjklmnpqrstvwxz])/ig;  // excluding y by default
    char = char || 'o';
    return text.replace(cons, '$1' + char + '$1');
}

console.log(translate("this is fun"));

I'll go for attempting the minimum amount of code while also taking uppercase letters at the beginning of words into account...

function translate(fullString) {    
    cons=new Array("b","B","c","C","d","D","f","F","g","G","h","H","j","J","k","K","l","L","m","M","n","N","p","P","q","Q","r","R","s","S","t","T","v","V","w","W","x","X","y","Y","z","Z");
    for(x in cons) {
        fullString=fullString.replace(new RegExp(cons[x], 'g'), cons[x] + "o" + cons[x].toLowerCase());
    }
    return fullString;
}

I'm sure someone with a better knowledge of regex than me could also reduce the size of the array :-)

function checkConsonants(letterToCheck) {
    var consonants = ['b', 'c', 'd', 'f', 'g', 'h', 'j', 'k', 'l', 'm', 'n', 'p', 'q', 'r', 's', 't', 'v', 'w', 'x', 'y', 'z'];
    var isConsonant = false;

    for (i = 0; i < consonants.length; i++) {
        if (letterToCheck == consonants[i]) {
            isConsonant = true;
        }
    }
    return isConsonant;
}

function translate(funString, letterO) {

    console.log('The original string is: "' + funString + '"');
    console.log('The separator is: "' + letterO + '"');

    var newString = '';

    for (var i = 0; i < funString.length; i++) {
        if (checkConsonants(funString[i])) {
            newString += funString[i] + letterO + funString[i];
        } else {
            newString += funString[i];
        }
    }
    console.log('The "rövarspråket" result is: ' + '"' + newString + '"');
}

translate('this is fun', 'o');

Take a look of this.
