Package description
The escape-string-regexp package is used to escape any characters that have special meaning in regular expressions. It takes a string and escapes characters that could be interpreted in a regex pattern, allowing the string to be used within a regex without triggering its special behavior.
Escaping special characters in strings for use in regular expressions
This feature is useful when you want to create a regular expression that includes literal strings that may contain characters that would normally be interpreted as special regex tokens. By escaping these characters, they are treated as literals in the regex pattern.
const escapeStringRegexp = require('escape-string-regexp');
const escapedString = escapeStringRegexp('Hello. How are you?');
// escapedString would be 'Hello\. How are you\?'This package provides similar functionality to escape-string-regexp by escaping special characters in strings for use in regular expressions. It is an alternative that can be used for the same purpose.
Another package that serves the same purpose as escape-string-regexp, regex-escape allows you to escape special characters in strings to safely use them in regular expressions.
