从NodeJS中的名称数组创建唯一名称

const uuidv4 = require('uuid').v4;
const crypto = require('crypto');

const names = ['John', 'Jane', 'Alice', 'Bob'];
const uniqueNames = [];

names.forEach(name => {
  let uniqueName = generateUniqueName(name);
  while (uniqueNames.includes(uniqueName)) {
    uniqueName = generateUniqueName(name);
  }
  uniqueNames.push(uniqueName);
});

function generateUniqueName(name) {
  // 使用UUID生成唯一名称
  // const uniqueName = uuidv4();

  // 使用时间戳和名称的组合生成唯一名称
  // const uniqueName = `${Date.now()}_${name}`;

  // 使用名称的哈希值生成唯一名称
  const hash = crypto.createHash('md5').update(name).digest('hex');
  const uniqueName = `${hash}_${name}`;

  return uniqueName;
}

console.log(uniqueNames);
