 In the Chrome console,
 invoke the function `alert` with an input string of `"Hello world!"`;
 
+    To invoke an alert that lives in the engine v8; we need to 
+    run `alert("Hi there!")`
+
+
 What effect does calling the `alert` function have?
 
+    In short: alert() interrupts the page to show a message and waits for the user to acknowledge it.
+
+    📢 The message you pass to alert() is displayed to the user.
+
+    ⏸️ JavaScript execution pauses until the user clicks OK.
+
+    🚫 The user can’t interact with the page while the alert is open (it blocks the UI).
+
+
+
 Now try invoking the function `prompt` with a string input of `"What is your name?"` - store the return value of your call to `prompt` in an variable called `myName`.
 
+
+    let myName = prompt("hello what is your name")
+    alert("hi " + myName)
+
+    The prompt function displays a modal dialog that captures user input. The value entered is stored in myName, and alert then displays a greeting that includes that value.
+
+
 What effect does calling the `prompt` function have?
 What is the return value of `prompt`?
+
+    Calling the prompt() function displays a modal pop-up dialog that:
+
+    * Shows a message to the user
+
+    * Includes a text input field
+
+    * Has OK and Cancel      buttons
+
+    * Blocks interaction with the page until the user responds
