How to understand javascript error debugging message

Question

I have used one function in my application which through error message.

This I have done to identify the error line number and file location.

That is fine it work good but I am confused for those line numbers because it has 2 value for each.

Please have look on one of same error message:

Error
    at Object.Core.initAlert (http://localhost/demo/core.js:205:22)
    at http://localhost/demo/app.js:26:10
    at _setImmediate (http://localhost/demo/async.js:182:20)
    at http://localhost/demo/async.js:234:13
    at http://localhost/demo/async.js:113:13
    at _arrayEach (http://localhost/demo/async.js:85:13)
    at _forEachOf (http://localhost/demo/async.js:112:9)
    at _each (http://localhost/demo/async.js:77:13)
    at Object.async.forEachOf.async.eachOf (http://localhost/demo/async.js:233:9)
    at Object.async.forEach.async.each (http://localhost/demo/async.js:210:22)

You can see at last of line there are two line numbers and I am confused here that which one is the line number for function statement. First one or second.

For ex. IN first line:

at Object.Core.initAlert (http://localhost/demo/core.js:205:22)

205 and 22 are there

Do anyone know about it....

Or is there any other way to track stack of execution in javascript.

The first one is the line number, the second is the column number — depperm

The first number is the line number, the second number is the column number.

The first number tells you the line number.

The second number represents the character starting position in that line where the error occurred.
