How to Verify Regex Matches for Entire Strings in JavaScript

Question:

You seek a JavaScript or jQuery method to validate whether a string complies with the regular expression ^([a-z0-9]{5,}$$ and return a boolean outcome. Despite using match(), you're uncertain if it can match the entire string rather than just a portion.

Answer:

Use regex.test() for Boolean Results:

If your goal is solely to obtain a true or false result, employ the regex.test() method:

console.log(/^([a-z0-9]{5,})$/.test('abc1')); // false
console.log(/^([a-z0-9]{5,})$/.test('abc12')); // true
console.log(/^([a-z0-9]{5,})$/.test('abc123')); // true
