# Unit 1: Lesson 5 - Coding Lab (Data Manipulation) ## Objective: The objective of this lab is to practice working with variables, including declaration, assignment, and reassignment, and to explore basic data manipulation with numbers and strings in JavaScript. ## Instructions ### Part 1: Variable Declaration and Assignment [1.1: 1 pt] 1. Declare a variable called `studentName` and assign it your name as a string. 2. Declare a variable called `age` and assign it your age as a number. 3. Declare a variable called `course` and assign it the string "Computer Science Principles." ### Part 2: Variable Reassignment [1.1: 1 pt] 1. Reassign the `studentName` variable to the name of a famous person. 2. Reassign the `age` variable to a different age. 3. Reassign the `course` variable to "Advanced Computer Science." ### Part 3: Data Manipulation with Numbers [1.4: 1 pt] 1. Declare a variable called `num1` and assign it a number (e.g., 10). 2. Declare a variable called `num2` and assign it another number (e.g., 5). 3. Create a new variable called `sum` and calculate the sum of `num1` and `num2`. Print the result to the console. 4. Create a new variable called `difference` and calculate the difference between `num1` and `num2`. Print the result to the console. 5. Create a new variable called `product` and calculate the product of `num1` and `num2`. Print the result to the console. 6. Create a new variable called `quotient` and calculate the quotient of `num1` divided by `num2`. Print the result to the console. #### Part 4: Data Manipulation with Strings [1.4: 1 pt] 1. Declare a variable called `sumMessage` and use string interpolation to assign it the string `sum result: ${sum}`. 1a. Use `console.log`, the `sumMessage` variable, and a string method to output the variable in uppercase 2. Declare a variable called `differenceMessage` and use string interpolation to assign it the string `difference result ${difference}`. 2a. Use `console.log`, the `differenceMessage` variable, and a string method to output the variable in uppercase 3. Declare a variable called `productMessage` and use string interpolation to assign it the string `product result ${product}`. 3a. Use `console.log`, the `productMessage` variable, and a string method to output the variable in uppercase 4. Declare a variable called `quotientMessage` and assign it the string `quotient result ${quotient}`. 4a. Use `console.log`, the `quotientMessage` variable, and a string method to output the variable in uppercase.
