如何在Chrome开发者工具中调试JavaScript API？

Question

I want to step into(egF11) Object.create() and see what is happening internally. Is there any way to achieve this in Chrome Dev tools?

var o = {name: 'pat'};
var p = Object.create(o);

Answer 1

Object.create is native code. You can't debug it as it's not written in javascript. Wedkit and firefox developers have coded it in C or C++

Answer 2

You can debug this code. Open Dev Tool in Chrome:

Windows: F12

Mac: ⌘ + Option + i

Edit your code and put the "debugger;" before.

debugger;
var o = {name: 'pat'};
var p = Object.create(o);

Navigate with F11
