console：trace() 静态方法

...any, ...data 可选

Zero or more objects to be output to console along with the trace. These are assembled and formatted the same way they would be if passed to the console.log() method.

function foo() {
  function bar() {
    console.trace();
  }
  bar();
}

foo();

In the console, the following trace will be displayed:

bar
foo
<anonymous>
