editUse a comment to annotate or explain code within a script. Use the // token
anywhere on a line to specify a single-line comment. All characters from the
// token to the end of the line are ignored. Use an opening /* token and a
closing */ token to specify a multi-line comment. Multi-line comments can
start anywhere on a line, and all characters in between the /* token and */
token are ignored. A comment is included anywhere within a script.
Grammar
SINGLE_LINE_COMMENT: '//' .*? [\n\r]; MULTI_LINE_COMMENT: '/*' .*? '*/';
