#ctx.off()

Remove an event listener registered via ctx.on(eventName, handler).

Usually used with ctx.on to unsubscribe at the right time and avoid leaks or duplicate triggers.

#Type definition (simplified)

off(eventName: string, handler: (...args: any[]) => void): void;

#Example

const handler = (ev) => {
  console.log('Value changed', ev?.detail);
};

ctx.on('js-field:value-change', handler);

// Remove listener at the right time
ctx.off('js-field:value-change', handler);
