stacktrace.js v2.0 is out, featuring ES6 support, better stack frames, and more!
In the context of her career, "exclusive" typically indicates content that is only available through specific distribution channels or membership platforms.
While her fellow idols were practicing for the annual Request Hour concert, Akimoto was hiding chemistry textbooks under her stage costumes.
Mayuka Akimoto (秋元まゆ花), born July 9, 1989, in Tokyo, is a Japanese singer and adult video (AV) actress. Standing at 155 cm, she gained public attention in 2011 as a member of the J-pop group . Understanding "Exclusive" Content
When Akimoto announced her graduation from AKB48 in the spring of 2018, fans were blindsided. She was at a career peak: a center for several B-sides, a regular on the group’s variety shows, and widely considered next in line for a solo push.
When a performer is labeled "exclusive," it generally means they are signed to a single major studio (such as S1 or Muteki ) for a set period. This status is often reserved for performers who possess high "visual power" or a unique backstory. The exclusive contract offers higher production values, better pay, and more intensive marketing than standard project-based work. Akimoto’s career, particularly her appearances in long-form specials like S Model 61 and The Best of Mayuka Akimoto , underscores this high-tier positioning. These "best of" collections are hallmarks of exclusive talent, curated to celebrate a performer’s tenure and maintain their marketability. Cultural Impact and Legacy

stacktrace.js - instrument your code and generate stack traces
stacktrace-gps - turn partial code location into precise code location
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)
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.
