Regex, detect no spaces in the string

This is my current regex check:

const validPassword = (password) => password.match(/^(?=.*\d)(?=.\S)(?=.*[a-zA-Z]).{6,}$/);

I have a check for at least 1 letter and 1 number and at least 6 characters long. However I also want to make sure that there are no spaces anywhere in the string.

So far I'm able to enter in 6 character strings with spaces included :(<img src=https://www.e-learn.cn/content/wangluowenzhang/"https://i.stack.imgur.com/tpPBh.png" alt="enter image description here">

Found this answer here, but for some reason in my code it's passing.

What is the regular expression for matching that contains no white space in between text?


It seems you need



    <li>^ - start of string</li> <li>(?=.*\d) - 1 digit (at least)</li> <li>(?=.*[a-zA-Z]) - at least 1 letter</li> <li>\S{6,} - 6 or more non-whitespace chars</li> <li>$ - end of string anchor</li> </ul>
