如何在不同场景中匹配特殊字符之间的文本

const strings = [
  "Useless information|| basic information|| advanced information|| super information|| no information",
  "Useless information|| basic information|| advanced information|| no information",
  "Useless information|| basic information|| no information",
  "Useless information|| no information"
];

strings.forEach((s) => {
  let parts = s.split("||");
  let result = [];
  if (parts.length === 2) {
    result.push(parts[0]);
  }
  if (parts.length === 3) {
    result.push(parts[1]);
  }
  if (parts.length > 3) {
    parts.shift();
    parts.pop();
    result = parts;
  }
  console.log(result);
});
