Simple, cross-browser [Error](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error) parser.
|
|
This library parses and extracts function names, URLs, line numbers, and column numbers from the given Error's `stack` as
|
|
an Array of [StackFrame](http://git.io/stackframe)s.
|
|
|
|
Once you have parsed out StackFrames, you can do much more interesting things. See [stacktrace-gps](http://git.io/stacktrace-gps).
|
|
|
|
Note that in IE9 and earlier, `Error` objects don't have enough information to extract much of anything. In IE 10, `Error`s
|
|
are given a `stack` once they're `throw`n.
