/**
 * @example
 * The expected way to use the switch since it relies on dynamic inputs, is to add new Inputs for the switch node
 * ```ts
 * const switchNode = new SwitchNode();
 * switchNode.addInput("foo", {
 *  type: AnySchema,
 * });
 *
 * switchNode.addInput("bar", {
 * type: AnySchema,
 * });
 *
 * //Now if the condition matches the name 'foo' it will output the value of the foo input
 * // If no condition matches, it will output the value of the `default` input
 *
 * ```
