# Standardized Debug

This proposal is at Stage 1 of the [TC39 Process](https://tc39.es/process-document/).

## Motivation

Different environments expose different APIs for interacting with debugger

facilities. Some of them do not expose any APIs for this at all. This proposal

aims to provide standardized debugging facilities across all ECMAScript

implementations. Additionally, the APIs are constrained to be identity

functions - that is, they return the value which is passed to them.

This proposal suggests adding the following meta-property-functions to ES:

- `debugger.log ( v )`

- `debugger.break ( [ v ] )`

Note that, like `import()`, they are only valid in call expression form. For

example, `x().then(debugger.break)` would be invalid. You would have to do

`x().then((v) => debugger.break(v))`. This limitation is in place to ensure

these methods (particularly `break`) are only ever invoked from ECMAScript code.
