+# --description--
+
+In this lab, you'll practice using functions by building a random password generator.
+
+**Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab.
+
+**User Stories:**
+
+1. You should create a function called `generatePassword` that takes a parameter. You can name the parameter whatever you like. 
+2. Your function should return a string which represents a randomly generated password. You should use the following string and different `Math` methods to help you return a new string with random characters in it: `ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()`. 
+3. You should define a variable called `password` and assign it the result of calling the `generatePassword` function with a numeric argument that represents the desired password length.
+4. You should have a `console.log` that logs the message `"Generated password:"` followed by the `password` variable.
+
+# --hints--
+
+You should have a `generatePassword` function with a parameter. You can name the parameter whatever you like.
+
+```js
+assert.isFunction(generatePassword);
+assert.lengthOf(generatePassword, 1);
+```
+
+Your `generatePassword` function should return a string.
+
+```js
+const result = generatePassword(5);
+assert.isString(result);
+```
+
+Your `generatePassword` function should return a new string that is the correct length.
+
+```js
+const length = 8;
+const password = generatePassword(length);
+assert.lengthOf(password, length);
+```
+
+Your function should return a randomly generated password with valid characters.
+
+```js
+const validChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()";
+const password = generatePassword(10);
+for (let char of password) {
+    assert.include(validChars, char);
+}
+```
+
+Your function should return a new random string each time it is called.
+
+```js
+const password1 = generatePassword(10);
+const password2 = generatePassword(10);
+assert.notStrictEqual(password1, password2);
+```
+
+You should have a `password` variable.
+
+```js
+assert.isDefined(password);
+```
+
+Your `password` variable should be a string.
+
+```js
+assert.isString(password);
+```
+
+You should call the `generatePassword` function with a numeric argument and store the returned password in the `password` variable.
+
+```js
+assert.isDefined(password);
+assert.isString(password);
+const testLength = password.length;
+assert.strictEqual(password.length, testLength);
+assert.match(password, /^[A-Za-z0-9!@#$%^&*()]+$/);
+```
+
+You should log the generated password to the console.
+
+```js
+const condition1 = /console\.log\(\s*["']Generated\s+password:\s*["']\s*\+\s*password\s*\);?/gm.test(code);
+const condition2 = /console\.log\(\s*`Generated\s+password:\s*\$\{password\}`\s*\);?/gm.test(code);
+assert.isTrue(condition1 || condition2);
+```
+

+

+
+# --solutions--
+
+```js
+const generatePassword = (length) => {
+    const chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()";
+    let password = "";
+    for (let i = 0; i < length; i++) {
+        const randomIndex = Math.floor(Math.random() * chars.length);
+        password += chars[randomIndex];
+    }
+    return password;
+};
+
+const password = generatePassword(12);
+console.log(`Generated password: ${password}`);
+```
