// Collect the data from the enduser
const response = prompt("What is your name?")

// Task. Convert the above `if - else` statement to an `OR` statement
const username2 = response || "guest";

// Return the appropriate response to the console
console.log(username2)

// Return the appropriate response to the screen
alert(username2)

// The Algorithmic Steps
// ------------------------------------------------------------------------

// Go to the `file explorer` of your development machine

// Find your js `app` file in the appropriately stored folder

// Double click on the accompanying html `index` file

// Your default browser window opens, the subject js `app` is executed

// ------------------------------------------------------------------------
// Note. The subject js `app` can now be executed ...
// Upon any changes to the underlying code ...
// Via the refresh feature of your browser window.
// ------------------------------------------------------------------------

// Next, the window prompts the enduser for a name entry via the `prompt` feature

// The user's response or lack thereof is stored in the constant `response`

// The enduser either enters a name, or leaves the prompt feature empty

// The variable `username1` is declared in a `let` statement

// A standard `if - else` statement tucks the enduser's response into the `username1` variable ...

// By setting the result received from the constant variable `response` to the variable `username1`.

// Finally, the console returns and confirms the contents of the variable `username1` via the `console` and `alert` window features.

// ------------------------------------------------------------------------
// Conversion
// ------------------------------------------------------------------------

// Convert the subject `if - else` statement to an `OR` statement

// Use the `shift backslash` key to create an `OR` relationship, as follows:

// entry-A `||` "entry-B"

// ;where the first entry or `operand` is either set or coerced by Javascript into a truthy value ie.) a valid string ...

// And, then read, stored, and returned.

// ------------------------------------------------------------------------
// Note. In this case the console returns `Roberto`.
// ------------------------------------------------------------------------

// Or,

// ;where if the first entry or `operand` cannot be coerced by Javascript into a truthy value ...

// ie.) the contents of the prompt is `a falsy value` such as null or empty ...

// Then, the second entry or `operand` is then read, stored, and returned via an `alert` box.

// ------------------------------------------------------------------------
// Note. In this case the `alert` returns `guest`.
// ------------------------------------------------------------------------

// STOP

// Set the constant to a Boolean value of `true`
const isEmailVerified = true;

// Collect the data from the enduser
const response = prompt("What is your name?")

// Declare a mutable variable
let username3;

// Set up an `if - else` statement
if (response) {
  if (isEmailVerified) {
    username3 = response;
  }
} else {
  username3 = "guest";
}

// Return the appropriate response to the console
console.log(username3)

// Return the appropriate response to the screen
alert(username3)

// Task. Convert the above `if - else` statement to an `AND` statement
const username4 = (isEmailVerified && response) || "guest";

// Return the appropriate response to the console
console.log(username4)

// Return the appropriate response to the screen

// entry-A `&&` "entry-B" || "guest"

// ;where the first entry or `operand` is either set or coerced by Javascript into a truthy value ie.) a valid string ...
