Simple regex is good for such thing.

"boooody".replace(/(\w)\1+/g, "$1");
// "body"

var words = [
    'boooody',
    'Steveeen',
    'uuuuuuser',
    'etccccc'
];

for (var i = 0, l = words.length; i < l; ++i) {
    var word = words[i].replace(/[^\w\s]|(.)(?=\1)/gi, ""); 
}

Try this:

str.replace(/(.)\1{1,}/g, "$1");
