-# Data Types Practice
-
-## Instructions
-
-Imagine you are building a shopping cart. Write some documentation on the data types that you would need to complete your shopping experience. How did you arrive at your choices?
+- Strings: To store text-based information such as product names, categories, and user details.
+- Numbers:To handle all quantities, prices, totals, and IDs.
+- Boolean:To represent true/false conditions in the cart.
+- Arrays:To store lists of related items, such as products in the cart.
+- Objects:To represent structured data like a single product, user, or order.

-# Fun with Functions
+# Challenge
+- method is something that belong to an object or a class. It is also defined within a class defination.
+while function is something that can be defined any where and used anywhere. A method can only be used to manipulate or something related to it to a class or its objects 
+# assignment
+```
+function funct1(a){
+    console.log(a);
+}
+```
+- or it can be written in the following way
 
-## Instructions
+```
+function funct2(a){
+    return a;
+}
+```
+- here is the function with defualt and normal parameters
 
-Create different functions, both functions that return something and functions that don't return anything.
-
-See if you can create a function that has a mix of parameters and parameters with default values.
+```
+function funct3(a=2,b){
+    console.log(a+b);

 # Operators
-
-## Instructions
-
-Play around with operators. Here's a suggestion for a program you can implement:
-
-You have a set of students from two different grading systems.
-
-### First grading system
-
-One grading system is defined as grades being from 1-5 where 3 and above means you pass the course.
-
-### Second grading system
-
-The other grade system has the following grades `A, A-, B, B-, C, C-` where `A` is the top grade and `C` is the lowest passing grade.
-
-### The task
-
-Given the following array `allStudents` representing all students and their grades, construct a new array `studentsWhoPass` containing all students who pass.
-
-> TIP, use a for-loop and if...else and comparison operators:
-
 ```javascript
 let allStudents = [
   'A',
