When in doubt, use `.parse()`.\n\n### Options\n\n- **allowImportExportEverywhere**: By default, `import` and `export`\n  declarations can only appear at a program's top level. Setting this\n  option to `true` allows them anywhere where a statement is allowed.\n\n- **allowReturnOutsideFunction**: By default, a return statement at\n  the top level raises an error. Set this to `true` to accept such\n  code.\n\n- **allowSuperOutsideMethod**: TODO\n\n- **sourceType**: Indicate the mode the code should be parsed in. Can be\n  either `\"script\"` or `\"module\"`.\n\n- **sourceFilename**: Correlate output AST nodes with their source filename.  Useful when generating code and source maps from the ASTs of multiple input files.\n\n- **startLine**: By default, the first line of code parsed is treated as line 1. You can provide a line number to alternatively start with. Useful for integration with other source tools.\n\n- **plugins**: Array containing the plugins that you want to enable.\n\n- **strictMode**: TODO\n\n- **ranges**: Adds a `ranges` property to each node: `[node.start, node.end]`\n\n- **tokens**: Adds all parsed tokens to a `tokens` property on the `File` node\n\n### Output\n\nBabylon generates AST according to [Babel AST format][].\nIt is based on [ESTree spec][] with the following deviations:\n\n> There is now an `estree` plugin which reverts these deviations\n\n- [Literal][] token is replaced with [StringLiteral][], [NumericLiteral][], [BooleanLiteral][], [NullLiteral][], [RegExpLiteral][]\n- [Property][] token is replaced with [ObjectProperty][] and [ObjectMethod][]\n- [MethodDefinition][] is replaced with [ClassMethod][]\n- [Program][] and [BlockStatement][] contain additional `directives` field with [Directive][] and [DirectiveLiteral][]\n- [ClassMethod][], [ObjectProperty][], and [ObjectMethod][] value property's properties in [FunctionExpression][] is coerced/brought into the main method node.\n\nAST for JSX code is based on [Facebook JSX AST][] with the addition of one node type:\n\n- `JSXText`\n\n[Babel AST format]: https://github.com/babel/babylon/blob/master/ast/spec.md\n[ESTree spec]: https://github.com/estree/estree\n\n[Literal]: https://github.com/estree/estree/blob/master/es5.md#literal\n[Property]: https://github.com/estree/estree/blob/master/es5.md#property\n[MethodDefinition]: https://github.com/estree/estree/blob/master/es2015.md#methoddefinition\n\n[StringLiteral]: https://github.com/babel/babylon/blob/master/ast/spec.md#stringliteral\n[NumericLiteral]: https://github.com/babel/babylon/blob/master/ast/spec.md#numericliteral\n[BooleanLiteral]: https://github.com/babel/babylon/blob/master/ast/spec.md#booleanliteral\n[NullLiteral]: https://github.com/babel/babylon/blob/master/ast/spec.md#nullliteral\n[RegExpLiteral]: https://github.com/babel/babylon/blob/master/ast/spec.md#regexpliteral\n[ObjectProperty]: https://github.com/babel/babylon/blob/master/ast/spec.md#objectproperty\n[ObjectMethod]: https://github.com/babel/babylon/blob/master/ast/spec.md#objectmethod\n[ClassMethod]: https://github.com/babel/babylon/blob/master/ast/spec.md#classmethod\n[Program]: https://github.com/babel/babylon/blob/master/ast/spec.md#programs\n[BlockStatement]: https://github.com/babel/babylon/blob/master/ast/spec.md#blockstatement\n[Directive]: https://github.com/babel/babylon/blob/master/ast/spec.md#directive\n[DirectiveLiteral]: https://github.com/babel/babylon/blob/master/ast/spec.md#directiveliteral\n[FunctionExpression]: https://github.com/babel/babylon/blob/master/ast/spec.md#functionexpression\n\n[Facebook JSX AST]: https://github.com/facebook/jsx/blob/master/AST.md\n\n### Semver\n\nBabylon follows semver in most situations. The only thing to note is that some spec-compliancy bug fixes may be released under patch versions.\n\nFor example: We push a fix to early error on something like [#107](https://github.com/babel/babylon/pull/107) - multiple default exports per file. That would be considered a bug fix even though it would cause a build to fail.\n\n### Example\n\n```javascript\nrequire(\"babylon\").parse(\"code\", {\n  // parse in strict mode and allow module declarations\n  sourceType: \"module\",\n\n  plugins: [\n    // enable jsx and flow syntax\n    \"jsx\",\n    \"flow\"\n  ]\n});\n```\n\n### Plugins\n\n| Name | Code Example |\n|------|--------------|\n| `estree` ([repo](https://github.com/estree/estree)) | n/a |\n| `jsx` ([repo](https://facebook.github.io/jsx/)) | `<a attr=\"b\">{s}</a>` |\n| `flow` ([repo](https://github.com/facebook/flow)) | `var a: string = \"\";` |\n| `typescript` ([repo](https://github.com/Microsoft/TypeScript)) | `var a: string = \"\";` |\n| `doExpressions` | `var a = do { if (true) { 'hi'; } };` |\n| `objectRestSpread` ([proposal](https://github.com/tc39/proposal-object-rest-spread)) | `var a = { b, ...c };` |\n| `decorators` (Stage 1) and `decorators2` (Stage 2 [proposal](https://github.com/tc39/proposal-decorators)) | `@a class A {}` |\n| `classProperties` ([proposal](https://github.com/tc39/proposal-class-public-fields)) | `class A { b = 1; }` |\n| `classPrivateProperties` ([proposal](https://github.com/tc39/proposal-private-fields)) | `class A { #b = 1; }` |\n| `exportExtensions` ([proposal 1](https://github.com/leebyron/ecmascript-export-default-from)), ([proposal 2](https://github.com/leebyron/ecmascript-export-ns-from)) | Proposal 1: `export v from \"mod\"` Proposal 2: `export * as ns from \"mod\"` |\n| `asyncGenerators` ([proposal](https://github.com/tc39/proposal-async-iteration)) | `async function*() {}`, `for await (let a of b) {}` |\n| `functionBind` ([proposal](https://github.com/zenparsing/es-function-bind)) | `a::b`, `::console.log` |\n| `functionSent` | `function.sent` |\n| `dynamicImport` ([proposal](https://github.com/tc39/proposal-dynamic-import)) | `import('./guy').then(a)` |\n| `numericSeparator` ([proposal](https://github.com/samuelgoto/proposal-numeric-separator)) | `1_000_000` |\n| `optionalChaining` ([proposal](https://github.com/tc39/proposal-optional-chaining)) | `a?.b` |\n| `importMeta` ([proposal](https://github.com/tc39/proposal-import-meta)) | `import.meta.url` |\n| `bigInt` ([proposal](https://github.com/tc39/proposal-bigint)) | `100n` |\n| `optionalCatchBinding` ([proposal](https://github.com/babel/proposals/issues/7)) | `try {throw 0;} catch{do();}` |\n\n### FAQ\n\n#### Will Babylon support a plugin system?\n\nPrevious issues: [babel/babel#1351](https://github.com/babel/babel/issues/1351), [#500](https://github.com/babel/babylon/issues/500).\n\nWe currently aren't willing to commit to supporting the API for plugins or the resulting ecosystem (there is already enough work maintaining Babel's own plugin system). It's not clear how to make that API effective, and it would limit out ability to refactor and optimize the codebase.\n\nOur current recommendation for those that want to create their own custom syntax is for users to fork Babylon.\n\nTo consume your custom parser, you can add to your `.babelrc` via its npm package name or require it if using JavaScript,\n\n```json\n{\n  \"parserOpts\": {\n    \"parser\": \"custom-fork-of-babylon-on-npm-here\"\n  }\n}\n```\n",
