## atomWithToggle
> `atomWithToggle` creates a new atom with a boolean as initial state & a setter function to toggle it.This avoids the boilerplate of having to setup another atom just to update the state of the first.
```tsimport { WritableAtom, atom } from 'jotai'
export function atomWithToggle(initialValue?: boolean): WritableAtom<boolean, boolean | undefined> {  const anAtom = atom(initialValue, (get, set, nextValue?: boolean) => {    const update = nextValue ?? !get(anAtom)    set(anAtom, update)  })  return anAtom as WritableAtom<boolean, boolean | undefined>}```
An optional initial state can be provided as first argument.
The setter function can have an optional arg to force a particular state (if you want to make a setActive function out of it for example).
Here is how it's used.
```tsimport { atomWithToggle } from 'XXX'
// will have an initial value set to trueconst isActiveAtom = atomWithToggle(true)```
And in a component :
```tsxconst Toggle = () => {  const [isActive, toggle] = useAtom(isActiveAtom)  return (    <>      <button onClick={() => toggle()}>isActive: {isActive ? 'yes' : 'no'}</button>      <button onClick={() => toggle(true)}>force true</button>      <button onClick={() => toggle(false)}>force false</button>    </>  )}```
## atomWithToggleAndStorage
> `atomWithToggleAndStorage` does the same as [`atomWithToggle`](#atom-with-toggle) but also persist the state anytime it changes in given storage using [`atomWithStorage`](../api/utils.mdx#atom-with-storage).Here is the source :
```tsimport { WritableAtom, atom } from 'jotai'import { atomWithStorage } from 'jotai/utils'
export function atomWithToggleAndStorage(  key: string,  initialValue?: boolean,  storage?: any): WritableAtom<boolean, boolean | undefined> {  const anAtom = atomWithStorage(key, initialValue, storage)  const derivedAtom = atom(    (get) => get(anAtom),    (get, set, nextValue?: boolean) => {      const update = nextValue ?? !get(anAtom)      set(anAtom, update)    }  )  return derivedAtom}```
And how it's used :
```tsimport { atomWithToggleAndStorage } from 'XXX'
// will have an initial value set to false & be stored in localStorage under the key "isActive"const isActiveAtom = atomWithToggleAndStorage('isActive')```
The usage in a component is also the same as [`atomWithToggle`](#atom-with-toggle).
