Try this:
const isValid = str => /^[a-zA-Z]{2,5}$/.test(str);
console.log(isValid('test')); // true
console.log(isValid('Test')); // true
console.log(isValid('test1')); // false
console.log(isValid('text@')); // false
console.log(isValid('123@#')); // false
console.log(isValid('Te12$')); // false

1@Tamil.S `/^[a-zA-Z]{2,5}$/.test('text@')` evaluates to `false`. – Michał Perłakowski Jun 07 '17 at 16:46

var regExp = /^[a-zA-Z]{2,5}$/; userInput="text%": if(userInput.test(regExp)) alert('yes'). else alert('no') – Tamil.S Jun 07 '17 at 16:55

@Tamil.S Try `var regExp = /^[a-zA-Z]{2,5}$/; var userInput = 'text%'; if (regExp.test(userInput)) alert('yes'); else alert('no');`. – Michał Perłakowski Jun 07 '17 at 17:01
