A simple toggle machine that can be used to toggle between two states.

The provided code is written in TypeScript and uses the XState library to create a state machine. XState is a library for creating, interpreting, and executing finite state machines and statecharts, as well as managing invocations of those machines as actors.

The createMachine function is imported from the XState library and is used to define a state machine. The toggleMachine is an exported variable that holds the state machine.

The state machine has an id of "toggle" and an initial state of "inactive". The initial property defines the state that the machine should be in when it starts.

The states property is an object that defines the different states that the machine can be in. In this case, there are two states: "active" and "inactive".

Each state (i.e., "active" and "inactive") has an on property, which is an object that defines the transitions between states. The on object has a property for each event that can cause a transition. In this case, there is only one event: "TOGGLE".

When the "TOGGLE" event occurs, the machine transitions to a different state. If the machine is in the "active" state and the "TOGGLE" event occurs, it transitions to the "inactive" state. Conversely, if the machine is in the "inactive" state and the "TOGGLE" event occurs, it transitions to the "active" state.

This state machine could be used, for example, to manage the state of a toggle button in a React application. The "active" state could represent the button being on, and the "inactive" state could represent the button being off. The "TOGGLE" event could be triggered whenever the button is clicked.
