Import path

import semmle.javascript.security.performance.ReDoSUtilSpecific

Provides classes for working with JavaScript programs, as well as JSON, YAML and HTML.

isEscapeClass	Holds if `term` is an ecape class representing e.g. `\d`. `clazz` is which character class it represents, e.g. “d” for `\d`.
isExcluded	Holds if the regular expression should not be considered.
isPossessive	Holds if `term` is a possessive quantifier. As javascript’s regexes do not support possessive quantifiers, this never holds, but is used by the shared library.
matchesAnyPrefix	Holds if the regex that `term` is part of is used in a way that ignores any leading prefix of the input it’s matched against. Not yet implemented for Javascript.
matchesAnySuffix	Holds if the regex that `term` is part of is used in a way that ignores any trailing suffix of the input it’s matched against. Not yet implemented for Javascript.

A module containing predicates for determining which flags a regular expression have.
