Given the JavaScript below: 01 function filterDOM(searchString){ 02 const parsedSearchString = searchString && searchString.toLowerCase(); 03 document.querySelectorAll('.account').forEach(account => { 04 const accountName = account.innerHTML.toLowerCase(); 05 account.style.display = accountName.includes(parsedSearchString) ? /* Insert code here */; 06 }); 07 } Which code should replace the placeholder comment on line 05 to hide accounts that do not match the search string?
Correct Answer: A
We have a ternary: account.style.display = accountName.includes(parsedSearchString) ? /* if true */ : /* if false */; Requirement: If the account matches the search string → show it. If it does not match → hide it. For display: Show: 'block' (or similar visible value). Hide: 'none'. So we want: account.style.display = accountName.includes(parsedSearchString) ? 'block' : 'none'; That corresponds to option A. Why others are wrong: B, C use values suitable for visibility, not display. D ('none' : 'block') inverts the logic, hiding matches and showing non-matches. ________________________________________
