在antlr的JavaScript库中，使用tree模块来创建ParseTree。以下是在JavaScript中使用antlr的示例代码：

const antlr4 = require('antlr4');
const YourGrammarLexer = require('./YourGrammarLexer.js').YourGrammarLexer;
const YourGrammarParser = require('./YourGrammarParser.js').YourGrammarParser;
const YourGrammarVisitor = require('./YourGrammarVisitor.js').YourGrammarVisitor;
const YourGrammarListener = require('./YourGrammarListener.js').YourGrammarListener;
const YourGrammarErrorListener = require('./YourGrammarErrorListener.js').YourGrammarErrorListener;

// Create the lexer and parser
const input = 'your_token_stream_here';
const lexer = new YourGrammarLexer(new antlr4.InputStream(input));
const parser = new YourGrammarParser(new antlr4.CommonTokenStream(lexer));

// Create the parse tree
parser.buildParseTrees = true; // This line is no longer needed in antlr4 version 4.9 and above
const tree = parser.your_grammar_rule_here();

// Use the parse tree
const visitor = new YourGrammarVisitor();
const result = visitor.visit(tree);
console.log(result);

在这个示例代码中，我们可以看到 buildParseTrees 属性的存在。从antlr 4.9版本开始，该属性默认为 true，所以“antlr 4.10.1对JavaScript似乎没有buildParseTrees属性”的问题已经不存在了。
