Example of EBNF-Like Syntax for ECMAScript

Program       ::= StatementList

StatementList ::= Statement | StatementList Statement

Statement     ::= VariableDeclaration | ExpressionStatement | IfStatement

VariableDeclaration ::= "var" Identifier ("=" Expression)? ";"

ExpressionStatement ::= Expression ";"

IfStatement   ::= "if" "(" Expression ")" Statement ("else" Statement)?

Expression    ::= Identifier | Literal | BinaryExpression

BinaryExpression ::= Expression Operator Expression

Operator      ::= "+" | "-" | "*" | "/"

Identifier    ::= /[a-zA-Z_][a-zA-Z0-9_]*/

Literal       ::= StringLiteral | NumericLiteral | BooleanLiteral

StringLiteral ::= '"' [^"]* '"' | "'" [^']* "'"

NumericLiteral ::= /[0-9]+(\.[0-9]+)?/

BooleanLiteral ::= "true" | "false"
