How to detect if a player jumped with the If statement in a local script?

the one I searched up on the internet:

humanoid:GetPropertyChangedSignal("Jump"):Connect(function()
    print(humanoid.Jump)
    -- code
end)

homemade:

local player = game.Player.LocalPlayer

if player.Humanoid.Jump == true then
    -- code
end

tell me if the one I made works
