替换对象数组中的字符

const data = [
  { id: 1, name: 'John Doe' },
  { id: 2, name: 'Jane Smith' },
  { id: 3, name: 'Alice Johnson' }
];

// 简单替换
const searchValue = 'John';
const replaceValue = 'Jack';
const newData = data.map(item => ({
  ...item,
  name: item.name.replace(searchValue, replaceValue)
}));

console.log(newData);
// 输出:
// [
//   { id: 1, name: 'Jack Doe' },
//   { id: 2, name: 'Jane Smith' },
//   { id: 3, name: 'Alice Johnson' }
// ]

// 条件替换
const conditionReplace = (name) => {
  if (name.includes('Smith')) {
    return name.replace('Smith', 'Smyth');
  }
  return name;
};

const newDataWithCondition = data.map(item => ({
  ...item,
  name: conditionReplace(item.name)
}));

console.log(newDataWithCondition);
// 输出:
// [
//   { id: 1, name: 'John Doe' },
//   { id: 2, name: 'Jane Smyth' },
//   { id: 3, name: 'Alice Johnson' }
// ]

// 正则表达式替换
const regexReplace = (name) => {
  return name.replace(/(\w+)\s(\w+)/, '$2, $1');
};

const newDataWithRegex = data.map(item => ({
  ...item,
  name: regexReplace(item.name)
}));

console.log(newDataWithRegex);
// 输出:
// [
//   { id: 1, name: 'Doe, John' },
//   { id: 2, name: 'Smyth, Jane' },
//   { id: 3, name: 'Johnson, Alice' }
// ]
