<ul style="text-[#01579b] space-y-1">
<li><strong>Signal.new():</strong> Creates a new signal object</li>
<li><strong>signal:connect(callback):</strong> Connects a callback function and returns a connection object</li>
<li><strong>signal:fire(...):</strong> Fires the signal with optional arguments</li>
<li><strong>connection:disconnect():</strong> Disconnects a specific connection</li>
<li><strong>signal:disconnect():</strong> Disconnects all connections from the signal</li>
<li><strong>Multiple Connections:</strong> One signal can have multiple connected callbacks</li>
<li><strong>Argument Passing:</strong> Signals can pass multiple arguments to connected callbacks</li>
