Returns "equal, ok".

This function intentionally avoids mutating the input AST so it can be called after the AST has been frozen (i.e.

For readability, the names of certain automatically-generated symbols are derived from the file name.

This does "IsIdentifierES5AndESNext(UTF16ToString(text))" without any allocations.

This does "IsIdentifier(UTF16ToString(text))" without any allocations.

If this returns true, then calling this expression captures the target of the property access as "this" when calling the function in the property.

See the "White Space Code Points" table in the ECMAScript standard.

The goal of this function is to "rotate" the AST if it's possible to use the left-associative property of the operator to avoid unnecessary parentheses.

Note: This function does not say whether the expression is side-effect free or not.

This function intentionally avoids mutating the input AST so it can be called after the AST has been frozen (i.e.

The given "expr" argument should be the operand of a "!" prefix operator (i.e.

This can be used when the returned type is either one or the other.

Wraps the provided expression in the "!" prefix operator.

Simplify syntax when we know it's used inside a boolean context This function intentionally avoids mutating the input AST so it can be called after the AST has been frozen (i.e.

This will return a nil expression if the expression can be totally removed.

Returns true if the result of the "typeof" operator on this expression is statically determined and this expression has no side effects (i.e.

"a = b".

"a += b".

This is sort of like an IIFE with a "/* @__PURE__ */" comment except it's an inline annotation on an expression itself without the nested scope.

The exports are stored on "module" and/or "exports".

All export names are known explicitly.

Some export names are known explicitly, but others fall back to a dynamic run-time object.

This file doesn't have any kind of export, so it's impossible to say what kind of file this is.

These help reduce unnecessary memory allocations.

This is similar to an EIdentifier but it represents a reference to an ES6 import item.

This represents an internal property name that can be mangled.

This is similar to EIdentifier but it represents class-private fields and methods.

This is used for both strings and no-substitution template literals to reduce the number of cases that need to be checked for string optimization code.

Each file is made up of multiple parts, and each part consists of one or more top-level statements.

This is an "export = value;" statement in TypeScript.

This object represents all of these types of import statements: import 'path' import {item1, item2} from 'path' import * as ns from 'path' import defaultItem, {item1, item2} from 'path' import defaultItem, * as ns from 'path' Many parts are optional and can be combined in different ways.

The decision of whether to export an expression using "module.exports" or "export default" is deferred until linking using this statement kind.

This is a stand-in for a TypeScript type declaration.

"enum ns { it }".

"enum ns { it = 'it' }".

"namespace ns { export namespace it {} }".

"namespace ns { export let it }".

This is for TypeScript "enum" and "namespace" blocks.
