Return an Boolean array by matching words in two arrays

The function

should return which of the keywords are present in the text in the form of boolean array like:
array: [true, false, false]
. based on the second argument to the function. Right now, I am able to return only the
values, I do not know how to return
values when the case is false. The code is below. The output should be [true, false, false]

{function keywordusage(str,strArr){
var count = [];
var found = true;
var notfound = false;
var words = str.split(' ');
var wordsLength = words.length;
var ArrLength = strArr.length;
for(var i = 0; i < ArrLength; i++){
for(var j = 0; j < wordsLength; j++){
return count;

document.write(keywordusage('Dive Into Python is a free book for experienced programmers', ['Python', 'python', 'scala']));}

function keywordusage(text, keywords) {
    var elements = text.split(" ");
    var result = Array();
    for (var i=0; i < keywords.length;i++){
        if (elements.indexOf(keywords[i]) >= 0)
            result[i] = true;
            result[i] = false;
    }//end of for loop
    return result;

var result = keywordusage('Dive Into Python is a free book for experienced programmers', ['Python', 'python', 'scala']);
