Rework Adobe Javascript code to use array

Need to know how to modify Javascript to use array instead of single variable in Adobe Acrobat.

Instead of a single string, I want to be able to use a TXT or CSV file, and extract all the strings stored in that TXT or CSV file. I think this means storing results in arrays, but I use SQL on a daily basis, not Javascript.

// Iterates over all pages and find a given string and extracts all
// pages on which that string is found to a new file.

var pageArray = ;
var stringToSearchFor = "Total";

for (var p = 0; p < this.numPages; p++) {
// iterate over all words
for (var n = 0; n < this.getPageNumWords(p); n++) {
if (this.getPageNthWord(p, n) == stringToSearchFor) {
pageArray.push(p);
break;
}
}
}

if (pageArray.length > 0) {
// extract all pages that contain the string into a new document
var d = app.newDoc(); // this will add a blank page - we need to
remove that once we are done
for (var n = 0; n < pageArray.length; n++) {
d.insertPages({
nPage: d.numPages - 1,
cPath: this.path,
nStart: pageArray[n],
nEnd: pageArray[n],
});
}

// remove the first page
d.deletePages(0);

}
