// Type definitions for non-npm package estree 1.0
// Project: https://github.com/estree/estree
// Definitions by: RReverser <https://github.com/RReverser>
// Definitions: https://github.com/DefinitelyTyped/DefinitelyTyped

// This definition file follows a somewhat unusual format. ESTree allows
// runtime type checks based on the `type` parameter. In order to explain this
// to typescript we want to use discriminated union types:
// https://github.com/Microsoft/TypeScript/pull/9163
//
// For ESTree this is a bit tricky because the high level interfaces like
// Node or Function are pulling double duty. We want to pass common fields down
// to the interfaces that extend them (like Identifier or
// ArrowFunctionExpression), but you can't extend a type union or enforce
// common fields on them. So we've split the high level interfaces into two
// types, a base type which passes down inherited fields, and a type union of
// all types which extend the base type. Only the type union is exported, and
// the union is how other types refer to the collection of inheriting types.
//
// This makes the definitions file here somewhat more difficult to maintain,
// but it has the notable advantage of making ESTree much easier to use as
// an end user.
