6.15 LAB: JavaScript password strength Write a function called isStrongPassword() in script.js that has a single password parameter. The function should return true only if all the following conditions are true: • The password is at least 8 characters long. • The password does not contain the string "password". Hint: Use indexOf() to search for "password". • The password contains at least one uppercase character. Hint: Call the string method charCodeAt(index) to get the Unicode value of each character in the password. If a character code is between 65 and 90 (the Unicode values for A and Z), then an uppercase character is found. If any of the above conditions are false, isStrongPassword () should return false. Below are example calls to isStrongPassword(): // false - Too short // false - Contains "password" // false - No uppercase characters isstrongPassword ("Qwerty") ; isStrongPassword ("passwordQwerty") isstrongPassword ("qwerty123") isstrongPassword("Qwerty123") // true To test your code in your web browser, call isstrongPassword() from the JavaScript console.

Question
I am having trouble with javascript code. I just don't know where to start (I found most of the chapter confusing). I have included image of question and my javascript. Please explain as clear as possible (step by step) so that I can understand the process completely.
Once the code is written...I go to chrome (my web browser), bring up the console and call the function...can you explain these steps as well. Thank you

### Objective:
Write a function called `isStrongPassword()` in `script.js` that has a single password parameter. The function should return `true` only if all the following conditions are met:
- **The password is at least 8 characters long.**
- **The password does not contain the string "password".**
*Hint:* Use `indexOf()` to search for "password".
- **The password contains at least one uppercase character.**
*Hint:* Call the string method `charCodeAt(index)` to get the Unicode value of each character in the password. If a character code is between 65 and 90 (the Unicode values for "A" and "Z"), then an uppercase character is found.
If any of the above conditions are false, `isStrongPassword()` should return `false`.
### Example Calls:
```javascript
isStrongPassword("Qwerty");
// false - Too short
isStrongPassword("passwordQwerty");
// false - Contains "password"
isStrongPassword("qwerty123");
// false - No uppercase characters
isStrongPassword("Qwerty123");
// true
```
### Testing:
To test your code in your web browser, call `isStrongPassword()` from the JavaScript console.
Transcribed Image Text:```javascript
function isStrongPassword(password) {
var isStrong = false;
if(password.length > 8 && passwd.indexOf("password") == -1) {
for(var i = 0; i < passwd.length; i++) {
var charCode = passwd.charCodeAt(i);
if(charCode >= 65 && charCode <= 90) {
isStrong = true;
}
}
}
return isStrong;
}
var password = "Qwerty";
var isStrong = isStrongPassword(password);
if(isStrong) {
print(password + " is strong");
} else {
print(password + " is not strong");
}
password = "passwordQwerty";
isStrong = isStrongPassword(password);
if(isStrong) {
print(password + " is strong");
} else {
print(password + " is not strong");
}
password = "Qwerty123";
isStrong = isStrongPassword(password);
if(isStrong) {
print(password + " is strong");
} else {
print(password + " is not strong");
}
password = "Qwerty123";
isStrong = isStrongPassword(password);
if(isStrong) {
print(password + " is strong");
} else {
print(password + " is not strong");
}
```
### Explanation:
This JavaScript code snippet defines a function `isStrongPassword` that checks the strength of a password based on specific criteria:
1. **Length Check**: The password must be more than 8 characters long.
2. **Exclusion of "password"**: The string "password" should not be part of the password.
3. **Uppercase Letter Check**: The password should contain at least one uppercase letter (A-Z).
The function then returns a boolean value indicating whether the password is strong or not.
The script tests multiple passwords using the `isStrongPassword` function and prints out whether each password is "strong" or "not strong".
