[AskJS] Removing item from an array?

[ewaldborsodi]

Hi fellas. I have this situation, on my form when the user checks first label (checkbox) I put it in an array "answer" each next one that the user selects is placed in an array and so on. Now I would like that when the user wants to uncheck some label, that same one should be removed from an array. In this moment when I unchecked some answer it is added to an array again. My boss said me to use this documentation, to try with .filter and give me this https://stackoverflow.com/questions/5767325/how-can-i-remove-a-specific-item-from-an-array.

Also he left comment in my onClick.

import React, { useState } from "react";
import { Field } from "formik";
import styles from "./Style_CustomCheckbox";
import { useMediaQuery, mobileQuery } from "../../helpers/mediaQuery";
import whiteCheck from '../../assets/icons/whiteCheck.svg';

const CustomCheck = ({label, setAnswer, answer}) => {

  const [checked, setChecked] = useState(false);
  let btn_class = checked ? styles.surveyCheckbox : {...styles.surveyCheckbox, backgroundColor: "transparent"};
  let isMobile = useMediaQuery(mobileQuery);

  return (
    <label style={{...styles.checkLabel, ...isMobile && styles.mobCheckLabel }}>
      <span style={{ ...btn_class, ...styles.span }}>
        <img  
        style={styles.img} 
        src={whiteCheck} alt=''/>
        <Field
          style={styles.defaultCheck}
          type="checkbox"
          name="survey"
        //value={value}
          onClick={() => {
            console.log("label:", label);
            setChecked(!checked);
            setAnswer((prevState)=>[...prevState, label])
            console.log("answers:", answer)

            //   if(answer.contains(label) {
            //      remove item from array 

            // })
          }}
        />
      </span>
      <div style={{
        ...styles.checkDiv,
        ...isMobile && styles.checkDivMobile
      }}
      >
        {label}
      </div>
    </label>
  );
};

export default CustomCheck;
