AngularsJS JavaScript Matching Words and Adding String

I have a long text in contentString.

In $scope.listKeyWords, I have some keywords (car, house, red, cool)

I need to match this keywords in my text and add some stuff like:

Input contentString:

Hello there, I have a very nice car. It is very cool.

Output expected:

Hello there, I have a very nice <u>car</u>. It is very <u>cool</u>.

[EDITED] [SOLUTION] thanks to @Barth Zalewski

for (var k = 0, word; word = $scope.listKeyWords[k]; k++) {
   var re = new RegExp(word, 'g');
   contentString = contentString.replace(re, "<u>" + word + "</u>");
}

How can I proceed?

Thanks for your help

for (var k = 0, word; word = $scope.listKeyWords[k]; k++) {
  contentString = contentString.replace(new RegExp("/\\b" + word + "\\b/"), "<u>" + word + "</u>");
}

The \b denotes a "word boundary" so that only whole words will be replaced.
