Как сделать проверку radioButton на JavaScript

document.querySelectorAll('input[name="knowledge"]').forEach(function(radio) {
  radio.addEventListener('change', function() {
    var value = this.value;
    var collapse_for_Study_Yes = document.getElementById('collapseforStudyYes');
 
    if (value === 'Study_Yes') {
      collapse_for_Study_Yes.classList.add('show');
    } else {
      collapse_for_Study_Yes.classList.remove('show');
    }
  });
});

document.querySelectorAll('input[name="knowledge"]').forEach(function(radio, i, a) {
    radio.addEventListener('change', function() {
    var collapse_for_Study_Yes = document.getElementById('collapseforStudyYes');
    if (this.value === 'Study_Yes') {
        collapse_for_Study_Yes.classList.add('show');
        this.value = 'Yes';
    } else {
        collapse_for_Study_Yes.classList.remove('show');
        [...a].find(_ => _ !== this).value = 'Study_Yes';
    }
  });
});

const ids = ['flexRadioStudyYes', 'flexRadioStudyNo', 'collapseforStudyYes'];
const [yes, no, clps] = ids.map(id => document.getElementById(id));
 
[yes, no].forEach(rad => {
    rad.addEventListener('change', e => {
        if (e.target === yes) {
            clps.classList.add('show');
            yes.value = 'Yes';
            return;
        }
        clps.classList.remove('show');
        yes.value = 'Study_Yes';
    });
});

const ids = ['flexRadioStudyYes', 'flexRadioStudyNo', 'collapseforStudyYes'];
