Method emitPostfixTypeOperand

internal/printer/printer.go:1991–1997

emitPostfixTypeOperand emits the operand of a postfix type (ArrayType, IndexedAccessType, OptionalType). It is equivalent to `emitTypeNode(operand, TypePrecedencePostfix)` except that it preserves a parsed `typeof X` operand without adding parentheses (e.g., `typeof C[K]` instead of `(typeof C)[K]`)

(operand *ast.TypeNode, parent *ast.Node)

// via the factory, so parsed postfix types preserve the source as written during round-trip
// emit while synthesized postfix types (e.g., from declaration emit) still get the parentheses.
func (p *Printer) emitPostfixTypeOperand(operand *ast.TypeNode, parent *ast.Node) {
	if ast.IsParseTreeNode(parent) && operand.Kind == ast.KindTypeQuery {
		p.emitTypeNode(operand, ast.TypePrecedenceTypeOperator)
		return
	}
	p.emitTypeNode(operand, ast.TypePrecedencePostfix)
}
