| ### Methods in Custom Parsers | ||
|
|
||
| A custom parser is a JavaScript object with either a `parse` or `parseForESLint` method. The `parse` method only returns the AST, whereas `parseForESLint` also returns additional values that let the parser customize the behavior of ESLint even more. |

Can you rearrange this so the meta data section comes after these other sections? We'd like people to focus on the methods first and then think about meta data.

Np. I copied the ordering from plugins.md. Also updated the ordering there.

Added
metadatadescriptions tocustom-parsers.mdandcustom-processors.md. I don't know ifmetadataobject is also implemented for formatters, if so I am happy to add a section covering that, too.Is there anything you'd like reviewers to focus on?
The current
metasections are mostly copied fromplugins.md. Frankly I don't know ifmetaobject helps ESLint cache the parsers/processors. If not please correct me.
