stacktrace.js v2.0 is out, featuring ES6 support, better stack frames, and more!
In this fast-paced adventure, players take on the role of a prisoner tasked with escaping a maximum-security facility. The primary antagonist is , a notoriously "not-so-vigilant" but still dangerous warden who has filled the prison with intricate traps, patrolling guards, and complex puzzles.
The game is structured as a series of levels—often up to 25 challenging obstacles—that test a player's reflexes and strategic thinking. Key Gameplay Features Classroom 6x - Barry Prison Escape - Google Drive: Sign-in

In version 1.x, We've switched from a synchronous API to an asynchronous one using Promises because synchronous ajax calls are deprecated and frowned upon due to performance implications.
All methods now return stackframes. This Object representation is modeled closely after StackFrame representations in Gecko and V8. All you have to do to get stacktrace.js v0.x behavior is call .toString() on a stackframe.
Use Case: Give me a trace from wherever I am right now
var error = new Error('Boom');
printStackTrace({e: error});
==> Array[String]
v1.x:
var error = new Error('Boom');
StackTrace.fromError(error).then(callback).catch(errback);
==> Promise(Array[StackFrame], Error);
If this is all you need, you don't even need the full stacktrace.js library! Just use error-stack-parser!
ErrorStackParser.parse(new Error('boom'));
Use Case: Give me a trace anytime this function is called
Instrumenting now takes Function references instead of Strings.
v0.x:
function interestingFn() {...};
var p = new printStackTrace.implementation();
p.instrumentFunction(this, 'interestingFn', logStackTrace);
==> Function (instrumented)
p.deinstrumentFunction(this, 'interestingFn');
==> Function (original)
v1.x:
function interestingFn() {...};
StackTrace.instrument(interestingFn, callback, errback);
==> Function (instrumented)
StackTrace.deinstrument(interestingFn);
==> Function (original)

Turn partial code location into precise code location
This library accepts a code location (in the form of a StackFrame) and returns a new StackFrame with a more accurate location (using source maps) and guessed function names.
Usage
var stackframe = new StackFrame({fileName: 'http://localhost:3000/file.min.js', lineNumber: 1, columnNumber: 3284});
var callback = function myCallback(foundFunctionName) { console.log(foundFunctionName); };
// Such meta. Wow
var errback = function myErrback(error) { console.log(StackTrace.fromError(error)); };
var gps = new StackTraceGPS();
// Pinpoint actual function name and source-mapped location
gps.pinpoint(stackframe).then(callback, errback);
//===> Promise(StackFrame({functionName: 'fun', fileName: 'file.js', lineNumber: 203, columnNumber: 9}), Error)
// Better location/name information from source maps
gps.getMappedLocation(stackframe).then(callback, errback);
//===> Promise(StackFrame({fileName: 'file.js', lineNumber: 203, columnNumber: 9}), Error)
// Get function name from location information
gps.findFunctionName(stackframe).then(callback, errback);
//===> Promise(StackFrame({functionName: 'fun', fileName: 'http://localhost:3000/file.min.js', lineNumber: 1, columnNumber: 3284}), Error)

Extract meaning from JS Errors
Simple, cross-browser 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 StackFrames.
Once you have parsed out StackFrames, you can do much more interesting things. See stacktrace-gps.
Note that in IE9 and earlier, Error objects don't have enough information to extract much of anything. In IE 10, Errors are given a stack once they're thrown.
