Prefer RegExp#test() over String#match() and RegExp#exec() ​
💼 This rule is enabled in the ✅ recommended config.
🔧💡 This rule is automatically fixable by the --fix CLI option and manually fixable by editor suggestions.
When you want to know whether a pattern is found in a string, use RegExp#test() instead of String#match() and RegExp#exec(), as it exclusively returns a boolean and therefore is more efficient.
