console中一些不常用的实用方法

console.group('分组1');
console.table(
  [
    {key1: 1,key2: 2,key3: 3},
    {key1: 1,key2: 2,key3: 3},
    {key1: 1,key2: 2,key3: 3}
  ],
  ['key1', 'key2'] /*可选:要显示的key,其它忽略*/
);
console.groupEnd('分组1');

//-------------------------

console.groupCollapsed('分组2'); /*默认关闭的分组*/
console.table(
  [
    {key1: 1,key2: 2,key3: 3},
    {key1: 1,key2: 2,key3: 3},
    {key1: 1,key2: 2,key3: 3}
  ],
  ['key1', 'key2'] /*可选:要显示的key,其它忽略*/
);
console.groupEnd('分组2');

//-------------------------

console.timeStamp(); //在时间轴中添加一个标记

//-------------------------

console.time('计时');
//do something
console.timeEnd('计时');

//-------------------------

//条件断点的妙用
object.x = 1;  //expression break point: console.table(object);
