JavaScript

function checkExtension(list, ext) {
  // Split the list into an array of strings
  var extensions = list.split(',');

  // Trim any extra spaces around the substrings
  for (var i = 0; i < extensions.length; i++) {
    extensions[i] = extensions[i].trim();
  }

  // Check if the variable is in the array
  for (var i = 0; i < extensions.length; i++) {
    if (extensions[i] === ext) {
      return true;
    }
  }

  return false;
}

// Example usage
console.log(checkExtension("avi, mp3, mp4", "avi")); // true
console.log(checkExtension("avi, mp3, mp4", "txt")); // false
