Why return /^[A-Za-z0-9].{8,}/.test('Passw0rd'); returns false?

Question

Regular Expressions

need to return false when
.test('')
has something other than [A-Za-z0-9] and if the string is less than 8 characters

Answer 1

point is redundant.
Now you return false if the first character is not [А-Za-z0-9] or any characters after the first one is less than 8.
Learn the regexps. It's easy to learn how to write them, much easier than reading and / or trying to combine them.)
