list of declared keywords.

GOOD BASIC STEPS TO REMEMBER

 // 1. Declare variables and capture input.
const adjective = prompt("Give me a compliment");
console.log( adjective );
// 2. Combine the input with other words to create a story.
const compliment = `<p>You are so right I am: ${adjective} just the so ...</p>`;
console.log( compliment );
// 3. Display the story as a <p> inside the <main> element.
let wordvomit = compliment + "LIES LIES LIES!!!";
let spreadwordvomit = wordvomit;
console.log( spreadwordvomit );
document.querySelector('main').innerHTML = spreadwordvomit ;

TO STRING LITERAL

const flavor = "Blueberry";
const type = "Smoothie";
const price = 4.99;

const drink = flavor + ' ' + type + ': ' + '$' + price;

CHANGE

const flavor = "Blueberry";
const type = "Smoothie";
const price = 4.99;

const drink = `${flavor} ${type}: $${price}`;
