Module sljs::ast

JavaScript AST structures

A Program is the root of an AST. A Program contains a BlockStatement which is a sequence of Statements. A Statement is a wrapper for Stmt enum with some additional information. A Stmt enumerates every possible statement, e.g. VariableDeclaration, IfStatement, ExpressionStatement, etc.

ExpressionStatement is an Expression wrapped into a statement. An Expression is a wrapper for Expr enum that enumerates all possible expressions, e.g. CallExpression, MemberExpression, Identifier, AssignmentExpression, etc.

One of Expr variants is FunctionExpression that wraps a Function with its own BlockStatement body.
