How to access a value from a for-loop in JavaScript beyond its scope

Hello there!

Within nested json-files, I have been utilizing the following function for iteration:

function organizePeopleGroups(People, container, parentObject) {
    _.each(People, function (item, index) {

        var peopleGuid =[];
        for (var peopleIterator= 0; peopleIterator< People.length; peopleIterator++) {
            peopleGuid[peopleIterator] = People[peopleIterator].Id;
        }
        item.parent = parentObject;
        //switch different people
        switchPerson(item.Name, parentObject, peopleGuid [index]);
        if (item.People) organizePeopleGroups(item.People, container, item);
    });
};

However, I am encountering an issue... The 'peopleGuid' attribute is inaccessible outside of the for-loop due to scope limitations. How can I efficiently pass this value into the 'switchPerson' function? Appreciate your help!

Answer №1

Here is an alternative approach:

 const personGuids = [];
for (let index = 0; index < People.length; index++) {
    personGuids.push({index:People[index].Id});
}
console.log('personGuids', personGuids);
