use .removeFromThreads in more than 100 threads inside a google app script - google-apps-script

Question

i have a script that removes every thread within a label and all sublabels.This was workng fine, but recently i got an error that says that the operation childrens[i].removeFromThreads(threads); can not be applied to more that 100 threads... How can i fix this?
function removingThreadsfromLabel() {
var parentlabelstring = 'THELabel';
var parentlabel = GmailApp.getUserLabelByName(parentlabelstring);
var childrens = children(parentlabel);
for (var i = 0; i < childrens.length; i++){
var threads = childrens[i].getThreads();
childrens[i].removeFromThreads(threads);
}
}
function children(parent) {
var name = parent.getName() + '/';
return GmailApp.getUserLabels().filter(function(label) {
return label.getName().slice(0, name.length) == name;
});
}
For now i have done the following, but it is not optimal...
function removingThreadsfromLabel() {
var parentlabelstring = 'THELabel';
var parentlabel = GmailApp.getUserLabelByName(parentlabelstring);
var childrens = children(parentlabel);
for (var i = 0; i < childrens.length; i++){
var threads = childrens[i].getThreads();
Logger.log(threads.length);
while (threads.length>100){
childrens[i].removeFromThread(threads[0]);
var threads = childrens[i].getThreads();
}
childrens[i].removeFromThreads(threads);
}
}

Ok, i figure out how to do it in batch, so it is better that my first solution:
function removingThreadsfromLabel() {
var batchSize = 100;
var parentlabelstring = 'THELabel';
var parentlabel = GmailApp.getUserLabelByName(parentlabelstring);
var childrens = children(parentlabel);
for (var i = 0; i < childrens.length; i++){
var threads = childrens[i].getThreads();
Logger.log(threads.length);
for (var j = 0; j < threads.length; j+=batchSize) {
childrens[i].removeFromThreads(threads.slice(j, j+batchSize));
}
var threads = childrens[i].getThreads();
childrens[i].removeFromThreads(threads);
}
