this is how i am doing

_changeValue(value) {
   this.setState({
     currentValue: !this.state.currentValue,
   });
   if(selectedQuesiton.includes(value)){
       selectedQuesiton = selectedQuesiton.filter(item => item !== value)
       }
       else{
         selectedQuesiton.push(value)
       }
       console.log(selectedQuesiton)
 }

i am using filter to check data is available in the array or not and if it is then it will just ignore that item in to new array which selectedQuesiton in your case

hope this works and if it does not then comment me
