$*$ Problem $5$: Password Strength Checker

$*$

$*$ We want to make it as easy as possible for users to create secure passwords.

$*$ To do this, we want to build a simple password strength checker that will

$*$ tell us if a password is strong enough.

$*$

$*$ Write a function, checkPasswordStrength$()$ that accepts a password string

$*$ and returns the score of the password based on the following rules:

$*1.$ At least $8$ characters long.

$*2.$ Contains at least one uppercase letter

$*3.$ Contains at least one lowercase letter.

$*4.$ Contains at least one digit.

$*$

$*$

$*$ Depending on how many of the above rules are met, the score will be

$*0,1,2,3$ or $4.$

$*$ if the type of value is not a string, return null

$*$

$*$ @param $\{$string$\}$ value $-$ a string containing the password to be checked

$*$ @returns $\{$number$\}-$ a number between $0$ and $4,$ inclusive

$*/$

function checkPasswordStrength$($value$)\{$

$//$ Replace this comment with your code...

$\}$ function checkPasswordStrength$($value$)\{$

if $($typeof value $!==$ 'string'$)\{$

return null;

$\}$

let score $=0$;

$//$ Rule $1$: Check length

if $($value$.$length $>=8)\{$

score$++$;

$\}$

$//$ Rule $2$: Check for uppercase letter

if $(/[$A$-$Z$]/.$test$($value$))\{$

score$++$;

$\}$

$//$ Rule $3$: Check for lowercase letter

if $(/[$a$-$z$]/.$test$($value$))\{$

score$++$;

$\}$

$//$ Rule $4$: Check for digit

if $(/\backslash$d$/.$test$($value$))\{$

score$++$;

$\}$

return score;

$\}$

$*$ Problem $6$: Password Strength Checker for any number of password strings

$*$

$*$ You are asked to score password strength in a list using your

$*$ checkPasswordStrength$()$ function from problem $5.$

$*$

$*$ Where checkPasswordStrength$()$ takes a single password string, the passwordStrengthChecker$()$

$*$ function takes a list of $*$any$*$ number of password strings, parses them,

$*$ filters out any invalid ones, and creates a list.

$*$

$*$ For example: given the following strings, "asd$123"$ and $"$zdS$2$sd$5$d$1$S$",$

$*$ a new list would be created of the following form $"[2,3]".$

$*$

$*$ Notice how the list has been enclosed in $[...]$ square brackets, and each

$*$ score is separated by a comma and space.

$*$

$*$ The passwordStrengthChecker$()$ function can take any number of arguments, but they must all

$*$ be strings. If any of the values can't be parsed by checkPasswordStrength$()($i$.$e$.,$ if

$*$ it returns null$),$ skip the value. For example:

$*$

$*$ passwordStrengthChecker$("$asd$123","$zdS$2$sd$5$d$1$S$",123)$ should return

$*"[2,3]"$ and skip the invalid value.

$*$

$*$ @param $\{$number$\}$ arguments $-$ any number of string duration arguments can be passed

$*$ @returns $\{$string$\}$
