# JavaScript stacktrace testing

Small collection of trivial JS scripts showing how classes/constructors and prototypes compares too simple objects with methods in regards to stacktraces.

Threw in a what I think of as "nested class" aswell inspired from [bluebird](https://github.com/petkaantonov/bluebird) stacktraces.

Split into sync / async sections. Not necessarily meaningfull, but I wanted them both for my own reference.

## synchronous actions

Stacktraces from calling methods synchronously.

### sync.js

Error thrown from a method on an object.

```bash

→ node sync.js

/stacktrace-testing/lib/greeter.js:15

	throw new Error('What does my stacktrace look like?');

	      ^

Error: What does my stacktrace look like?

    at Object.sayHello (/stacktrace-testing/lib/greeter.js:15:8)

    at Object. (/stacktrace-testing/sync.js:3:9)

    at Module._compile (module.js:460:26)

    at Object.Module._extensions..js (module.js:478:10)

    at Module.load (module.js:355:32)

    at Function.Module._load (module.js:310:12)

    at Function.Module.runMain (module.js:501:10)

    at startup (node.js:124:16)

    at node.js:842:3

```

### sync-class.js

Error thrown from a method on a class.

```bash

→ node sync-class.js

/stacktrace-testing/lib/greeter.js:15

	throw new Error('What does my stacktrace look like?');

	      ^

Error: What does my stacktrace look like?

    at Greeter.sayHello (/stacktrace-testing/lib/greeter.js:15:8)

    at Object. (/stacktrace-testing/sync-class.js:4:7)

    at Module._compile (module.js:460:26)

    at Object.Module._extensions..js (module.js:478:10)

    at Function.Module.runMain (module.js:501:10)

    at startup (node.js:124:16)

    at node.js:842:3

```

### sync-nested.js

Error thrown from a method called on an object using another object.

```bash

→ node sync-nested.js

/stacktrace-testing/lib/shouter.js:6

	throw new Error('Necessary with $ in function name?');

	      ^

Error: Necessary with $ in function name?

    at Function.Module.runMain (module.js:501:10)

    at startup (node.js:124:16)

    at node.js:842:3

```

### sync-nested-class.js

Error thrown from a method called on an class which uses another object.

```bash

→ node sync-nested-class.js

/stacktrace-testing/lib/shouter.js:6

	throw new Error('Necessary with $ in function name?');

	      ^

Error: Necessary with $ in function name?

## asynchronous actions

Stacktraces from calling methods asynchronously.

### async.js
