Parameter	Expected type	Description
value	String	String to sanitize

This method will not be accessible from outside the source file since VerEx() returns an instance of the class rather than the class itself.

const stringToEscape = '(http://example.com?arg=foo+bar)';

// => '\(http:\/\/example.com\?arg\=foo\+bar\)'
console.log(VerbalExpression.sanitize(stringToEscape));

sanitize is a static method on the VerbalExpression class. However, it is also exposed as VerEx().sanitize.

add

Append a literal expression to the object.

Parameter	Expected type	Description
value (defaults to '')	String	Expression to add to the object

const expr = VerEx();
expr.add('(foo)?(?:bar)*');

console.log(expr); // => /(foo)?(?:bar)*/gm
