How can I make a long list find-change only on Master

Question

Hi everyone
I got this script:
var myDocuments = app.documents.everyItem();
var myLayers = myDocuments.layers.everyItem();
//Locked text frames on master spreads are not touched.
//If you want to unlock them you have to add something like this:
//Unlock ALL page items in every document on spreads and master spreads (optional):
myDocuments.pageItems.everyItem().locked = false;
var myPageItemsOnNormalSpreads = myDocuments.spreads.everyItem().pageItems.everyItem();
//Unlock the layers (optional)
myLayers.locked = false;
//Lock all first level page items on normal spreads
//That leaves the page items on master spreads unlocked:
myPageItemsOnNormalSpreads.locked = true;
//Now for the GREP part:
app.findChangeGrepOptions.includeMasterPages = true;
app.findGrepPreferences = changeGrepPreferences = null;
app.findGrepPreferences.findWhat = "\\b20\\d+\\b";
//Do the search on "all open document" level
//That will return an array of arrays:
var myTarget = myDocuments.findGrep();
//Flattening the myTarget array:
var flattenedFoundArray = [];
for(var n=0;n<myTarget.length;n++){
    flattenedFoundArray = flattenedFoundArray.concat(myTarget[n]);
//Change contents of found texts in flattened array:
for(var n=flattenedFoundArray.length-1;n>=0;n--){
    flattenedFoundArray[n].contents = String(Number(flattenedFoundArray[n].contents) + 1);
//Unlock all objects on normal spreads:
myPageItemsOnNormalSpreads.locked = false;
//Reset GREP find and change prefs:
app.findGrepPreferences = changeGrepPreferences = null;

I change it into this, aim to make a mulit items of find-change only on master

//===============================================================================
only what I can do is repeat and repeat again
is that another perfect solution to do that?

Try this,
findChange("USA", "CHINA");
findChange("Washington DC", "Beijing");
function findChange (findWhat, changeContent){
    var myDocuments = app.documents.everyItem();
    var myLayers = myDocuments.layers.everyItem();
    //Locked text frames on master spreads are not touched.
    //If you want to unlock them you have to add something like this:
    //Unlock ALL page items in every document on spreads and master spreads (optional):
    myDocuments.pageItems.everyItem().locked = false;
    var myPageItemsOnNormalSpreads = myDocuments.spreads.everyItem().pageItems.everyItem();
    //Unlock the layers (optional)
    myLayers.locked = false;
    //Lock all first level page items on normal spreads
    //That leaves the page items on master spreads unlocked:
    myPageItemsOnNormalSpreads.locked = true;
    //Now for the GREP part:
    app.findChangeGrepOptions.includeMasterPages = true;
    app.findGrepPreferences = changeGrepPreferences = null;
    if(findWhat)app.findGrepPreferences.findWhat = findWhat;
    //Do the search on "all open document" level
    //That will return an array of arrays:
    var myTarget = myDocuments.findGrep();
    //Flattening the myTarget array:
    var flattenedFoundArray = [];
    for(var n=0;n<myTarget.length;n++){
        flattenedFoundArray = flattenedFoundArray.concat(myTarget[n]);
    //Change contents of found texts in flattened array:
    for(var n=flattenedFoundArray.length-1;n>=0;n--){
        if(changeContent)flattenedFoundArray[n].contents = changeContent;
    //Unlock all objects on normal spreads:
    myPageItemsOnNormalSpreads.locked = false;
    //Reset GREP find and change prefs:
    app.findGrepPreferences = changeGrepPreferences = null;
