Prefer String#replaceAll() over regex searches with the global flag

💼 This rule is enabled in the ✅ recommended config.

🔧 This rule is automatically fixable by the --fix CLI option.

The String#replaceAll() method is both faster and safer as you don't have to use a regex and remember to escape it if the string is not a literal. And when used with a regex, it makes the intent clearer.

Fail

string.replace(/RegExp with global flag/igu, '');

string.replace(/RegExp without special symbols/g, '');

string.replace(/\(It also checks for escaped regex symbols\)/g, '');

string.replace(/Works for u flag too/gu, '');

string.replaceAll(/foo/g, 'bar');

Pass

string.replace(/Non-global regexp/iu, '');

string.replace('Not a regex expression', '')

string.replaceAll('string', '');

string.replaceAll(/\s/g, '');

string.replaceAll('foo', 'bar');
