Hey there, sorry you’ve been stuck on this for a full day—let’s get this sorted out! That error message tells us the JavaScript parser hit something it didn’t expect on line 24 (your onSearchChange line) and was expecting a comma instead. Here are the most common fixes to check:

• Check for missing commas in object literals
  If onSearchChange is part of an object (like React component props or a config object), the property before it might be missing a trailing comma. For example:

  // ❌ Wrong: Missing comma after the previous property
  const searchConfig = {
    inputPlaceholder: "Type to search"
    onSearchChange: (query) => { /* your logic */ }
  }
  
  // ✅ Correct: Add the trailing comma
  const searchConfig = {
    inputPlaceholder: "Type to search",
    onSearchChange: (query) => { /* your logic */ }
  }
  

• Double-check arrow function syntax
  If onSearchChange is an arrow function, make sure you haven’t messed up parentheses or braces. Common mistakes include:

  • Missing parentheses around multiple parameters (or destructured parameters)
  • Accidental extra brackets wrapping the function

  // ❌ Wrong: Missing parentheses for destructured param
  const onSearchChange = { query } => { console.log(query) }
  
  // ✅ Correct: Add parentheses
  const onSearchChange = ({ query }) => { console.log(query) }
  

• Inspect the line BEFORE line 24
  Sometimes the actual error is on the line above, but the parser only catches it when it reaches line 24. Check line 23 for:

  • Unclosed strings (forgot a quote)
  • Unclosed parentheses or curly braces
  • A missing semicolon that’s causing the parser to misinterpret the next line

Take a slow pass through those lines—small syntax typos like these are easy to miss when you’ve been staring at code for hours!
