API

$3

- debug()
- compressConditonalExpressions()
- compressCommaOperators()
- convertComputedToStatic()
- unshorten()
- expandBoolean()
- normalizeIdentifiers()

#### .debug()

Insert a debugger statement into a function.

#### Example

`js
$script(fnSelector).debug();
`

#### .compressConditonalExpressions()

Transform conditional expressions that have been reduced to testing only a literal value into the appropriate branch, e.g. var a = true ? 1 : 2; into var a = 1;

#### Example

`js
$script.compressConditonalExpressions();
`

#### .compressCommaOperators()

For comma operator expressions that include literal values, eliminate all but the rightmost expression, e.g. var a = true, false, 1, 2, "hello"; into var a = "hello";

#### Example

`js
$script.compressCommaOperators();
`

#### .convertComputedToStatic()

Turn computed member expressions into static member expressions, e.g. window["document"] into window.document

#### Example

`js
$script.convertComputedToStatic();
`

#### .unshorten()

Remove declaration statements like var r = require; and transform all references to the shortened identifier into the original.

#### Example

`js
$script(targetDeclaration).unshorten();
`

#### .expandBoolean()

Expands !1 and !0 into false and true

#### Example

`js
$script.expandBoolean();
`

#### .normalizeIdentifiers()

Transform all identifiers into consistent, memorable identifiers like $$abruptBrother

#### Example

`js
$script.normalizeIdentifiers();
