How would I check if a player has something that is listed within a table?

This is a Script that is located in ServerScriptService

game.Players.PlayerAdded:Connect(function(client) -- When player is added to Players service
    client.CharacterAdded:Connect(function(char) -- when that player's character is added

        local Vests = -- Vest locations
{["TanVest"] = char:FindFirstChild("TanVest");
     ["BlackVest"] = char:FindFirstChild("BlackVest";
} -- Vest locations

        local charChildren = char:GetChildren() -- getting children of the character(This is a table by way it :GetChildren() returns a table specifically a dictionary)

        local blackVest = table.find(charChildren, Vests.BlackVest) -- looks through the character table which are objects for the black vest
        local tanVest = table.find(charChildren, Vests.TanVest) -- looks through the character table which are objects for the tan vest

        if blackVest then -- checks whether the player has a blackvest if true then it runs "Player has a black vest" You can put some code to increase the character's health
            print("Player has a BlackVest")
        elseif tanVest then -- if tan vest if found then
            print("Player has TanVest")
        else -- if no vests were found then
            print("Player has no vest")
        end
    end)
end)

Notes

GetChildren has no parameters. All it does is return a table of the Instance which is getting the Children Instance:GetChildren().

Example:

local Children = Instance:GetChildren()
print(Children) -- This returns a table in the output

for index = #Vests, 0, -1 do
    if Character:FindFirstChild(Vests[index]) then
        --code
    end
end

or

for i,v in ipairs(Vests) do
    if Character:FindFirstChild(v) then
        --code
    end
end

does that work?
