here what I did. :)

// 1. Attach this file -- practice.js -- to the index.html file using a <script> tag

// 2. In this JavaScript file, add a prompt dialog to capture input from the user and store it in a variable

// 3. Add a second a prompt dialog to capture input from the user and store it in a second variable

// 4. Create a third variable and which combines an uppercase version values in the two other variables separated by a space. For example, if the first two variables contain "sally" and "forth", this third variable should contain the string value "SALLY FORTH"

// 5. Create a fourth variable to store a number. The number should be the total number of characters in the third variable.

// 6. Add an alert dialog box that says "The string '[insert value of third variable here]' is X number of characters long." For example, if the third variable contained the string "SALLY FORTH" then the alert dialog should says "The string 'SALLY FORTH' is 11 characters long."

//solution

let yourName = prompt('Hey! What\'s your name'); let age = prompt('what\'s your age bruh?');

//experiment part // const yourNameAge = yourName.toUpperCase() + ' ' + age.toUpperCase();

const yourNameAge = (yourName + ' ' + age).toUpperCase();

const howMany = yourNameAge.length;

alert('The string' + ' is ' + yourNameAge.length + ' characters long' );

// console.log(howMany);
