简单的js 数组去重方法

function unique ( arr,model ) { //数组去重
  let res = [arr[0]];
  console.log(res)
  for (let i = 0; i < arr.length; i++) {
    let repeat = false;
    for (let j = 0; j < res.length; j++) {
      if (arr[i][model] == res[j][model]) {
        repeat = true;
        break;
      }
    }
    if (!repeat) {
      res.push(arr[i]);
    }
  }
  return res;
}
