How to make a GetChildrenWhichEquals?

You can write a function for it: GetChildrenWhichEquals returns a table with all the value objects that equal number

function GetChildrenWhichEquals(parent, number)
    local childrenWithValue = {}

    --go through all the parents children:
    for _, child in pairs(parent:GetChildren()) do

        -- if child is a value object then
        if  child.ClassName:sub(-5) == "Value" then
            --check if the child's value equals value specified
            if child.Value == number then
                table.insert(childrenWithValue, number)
            end
        end

    end

    return childrenWithValue 
end

local leaderstats = game.Players.LocalPlayer.leaderstats

local children = GetChildrenWhichEquals(leaderstats, 2)
