Boolean Helpers

Boolean Helpers are methods available on Signal instances that contain boolean values. These helpers provide a convenient way to toggle the state of a boolean reactive variable.

toggle

Switches the boolean value of the Signal to its opposite state.

Syntax

signal.toggle()

Returns

boolean - The new value after toggling.

Usage

import { Signal } from '@semantic-ui/reactivity';

const isActive = new Signal(false);
isActive.toggle();

Example

Notes

• The toggle() method is particularly useful for managing binary states in your application, such as showing/hiding elements, enabling/disabling features, or switching between two modes.
• It provides a clean and readable way to flip boolean states without explicitly checking and setting the opposite value.
• Remember that like all Signal modifications, using toggle() will trigger any reactive computations that depend on this variable.
