How to quickly find the function to debug by JavaScript

This article will explain in detail how JavaScript can quickly find the function to debug. Xiaobian thinks it is quite practical, so share it with you as a reference. I hope you can gain something after reading this article.

Quickly find functions to debug

If you want to break points in a function, the two most common ways are:

Find lines in the console and add breakpoints

Add debugger to code

In both solutions, you must click in the file to debug a particular line.

It may be less common to break points using the console. Using debug(funcName) in the console, the code stops when the incoming function is reached.

This debugging method is fast, but the downside is that it doesn't work with private or anonymous functions. But aside from private and anonymous functions, this is probably the fastest way to find debugging functions. (Note: This function is not the same thing as console.debug.)

var func1 = function() { func2(); }; var Car = function() { this.funcX = function() { this.funcY(); } this.funcY = function() { this.funcZ(); } } var car = new Car();

Enter debug(car.funcY) in the console, and when car.funcY is called, it stops in debug mode:
