export const useArray = <V>(array:V[]) =>{
  const [value, setValues] = useState(array)

  const clear = ():void =>{
    setValues([])
  }

  const  removeIndex = (index:number):void =>{
    const newValue = [...value]
    newValue.splice(index,1)
    setValues(newValue)
  }

  const add = (item:V):void =>{
    const newValue = [...value]
    newValue.push(item)
    setValues(newValue)
  }

  return {value,clear,removeIndex,add}
}
