+## Exercise 1: Javascript Syntax Quiz
+Create a variable called firstName, that has your first name as it's value. 
+Then, create a variable called lastName, that has your last name as it's value.
+Using the console.log() function, print the two variables together.

 ## Operators
 Operators in JavaScript perform actions on values and variables. 
 These include arithmetic, comparison, logical, and assignment operators.

+## Exercise 3: Creating Functions
+Create your own array of food items.
+Then, write a function findFood() that takes in the array and a food item.
+It will loop through the array and return true if the item exists in the array, and false otherwise.

 ## Callbacks
 Callbacks are functions passed as arguments to other functions. They are commonly used for asynchronous programming and event handling.

+## Exercise 4: Async await practice
+
+Create an async function fetchData that simulates an API call to fetch user data. The function should return a promise that resolves after 2 seconds with a user object containing name and email.
+
+Then, write another async function displayUser that uses await to call fetchData and logs the user's information to the console.
