Code in '14. HtmlChatListener.js' does not produce the same result as seen on the screenshot

Code in '14. HtmlChatListener.js' does not produce the same result as on the screenshot.
The result is 'john SHOUTS:' without the emoji.
I think that this.Res.write(ctx.text ); is missing in exitEmoticon()

Error in 'Executing the instructions on Linux/Mac OS'

the command in line 5. (export CLASSPATH ...) from the snippet does not work because there are spaces after and before =.

Incorrect links in the table of content

For example, link '12. Setting Up the Chat Project in Javascript' in ToC is pointing to '14. HtmlChatListener.js'

TEXT in 9. Laxer Rules no work

Has error(50):: syntax error: ']' came as a surprise to me

error(50):: syntax error: mismatched input ')' expecting SEMI while matching lexer rule

js project has import errors

import ChatLexer from './ChatLexer.js';
       ^^^^^^^^^
SyntaxError: The requested module './ChatLexer.js' does not provide an export named 'default'

This is what I am getting while trying to run the js project, I believe it could be due to change in how antlr is building for the js environment now. I have been trying to import these generated files but to no avail.
