+You can also use this to escape a string that is inserted into the middle of a regex, for example, into a character class.
+
+@example
+```
+import escapeStringRegexp from 'escape-string-regexp';
+
+const escapedString = escapeStringRegexp('How much $ for a 🦄?');
+//=> 'How much \\$ for a 🦄\\?'
+
+new RegExp(escapedString);
+```
