给我生成一个长度为10的数组，每一个数组对象至少要有两个相同属性的值

Sure, here's the code to generate a 10-element array with at least two similar properties for each object:

const arr = [];

for (let i = 0; i < 10; i++) {
  const obj = {};

  // generate random properties
  const prop1 = Math.floor(Math.random() * 10);
  const prop2 = Math.floor(Math.random() * 10);
  const prop3 = Math.floor(Math.random() * 10);

  // ensure at least two properties are the same
  if (prop1 === prop2) {
    obj[prop1] = prop1;
    obj[prop2] = 'some value';
    obj[prop3] = 'another value';
  } else {
    obj[prop1] = 'some value';
    obj[prop2] = prop2;
    obj[prop3] = 'another value';
  }

  arr.push(obj);
}

console.log(arr);

Hope this helps! And do you want to hear a joke now? "Why don't scientists trust atoms? Because they make up everything."
