+Practice Problem #1
+
+Exercise 1: Retrieve and Add Two Code Points
+Objective: Extract the Unicode code points of the first two characters of a string,
+add them together, and return the result.
+
+Instructions:
+Write a program that takes a string with at least two characters.
+Use charCodeAt to get the Unicode code points of the first two characters.
+Add the two code points together and assign the result to a variable named sumCodePoints.
+Input:
+let inputString = "Hi";
+
+Expected Output:
+sumCodePoints: 177 // 'H' = 72, 'i' = 105, 72 + 105 = 177
+
+Exercise 2: Generate a String from Two Code Points
+Objective: Take two numeric Unicode code points,
+convert them to characters using String.fromCharCode,
+and combine them into a single string.
+
+Instructions:
+Write a program that accepts two numeric Unicode code points.
+Use String.fromCharCode to convert each code point to its corresponding character.
+Combine the two characters into a single string and assign it to a variable named combinedString.
+Input:
+let codePoint1 = 65;
+let codePoint2 = 66;
+
+Expected Output:
+combinedString: "AB" // 65 = 'A', 66 = 'B', combined = "AB"
+
+Exercise 3: Find the Character Difference
+Objective: Extract the Unicode code points of two given characters from a string
+and calculate the absolute difference between them.
+
+Instructions:
+Write a program that takes a string with at least two characters and two specified indices.
+Use charCodeAt to find the Unicode code points of the characters at the specified indices.
+Calculate the absolute difference between the two code points and assign it to a variable named codePointDifference.
+Input:
+let inputString = "Cat";
+let index1 = 0;
+let index2 = 2;
+
+Expected Output:
+codePointDifference: 16 // 'C' = 67, 't' = 116, |67 - 116| = 16
+
+
+
+Practice Problem #2
+
+Objective
+Practice converting characters from strings to Unicode code points
+using charCodeAt and converting Unicode code points back to characters
+using String.fromCharCode.
+
+Instructions:
+You will complete three tasks to explore the relationship
+between characters and their Unicode code points.
+Write JavaScript code to complete each task,
+ensuring you assign your results to the specified variables.
+Log all results to the console.
+
+Tasks:
+Task 1: Extract Code Points from Characters
+Take the string "Code".
+Use charCodeAt to extract the Unicode code points of the first and third characters.
+Assign the results to variables named firstCodePoint and thirdCodePoint.
+
+Task 2: Create a Word from Code Points
+Use the Unicode code points 72, 101, 108, and 108 (corresponding to the characters H, e, l, and l).
+Use String.fromCharCode to create the word "Hell".
+Assign the result to a variable named wordFromCodePoints.
+
+Task 3: Swap First and Last Characters
+Take the string "Launch".
+Extract the Unicode code points of the first and last characters using charCodeAt.
+Use String.fromCharCode to swap these characters and create a new string: "hauncL".
+Assign the result to a variable named swappedString.
