Lesson 14 Function Argument in JavaScript

In the last lesson, we have discussed functions and its purpose, and we have learned how we can declare the function.
In this lesson, we are going a little bit deeper into the function and will discuss in detail about how we can define a function with arguments.

Lesson 15 Function Return Value

In this lesson, we are going to focus on last and another important concept of function that is return value.
So in this lesson, we are going to learn what the return keyword is and how do we write functions that use the return value.

Lesson 16 Arrays In JavaScript

In this lesson, we are going to introduce array in JavaScript and we are going to learn how we can utilize it. So in this lesson, we will discuss our first main data structure which is something called the array.
We will learn how we can code using arrays.

Lesson 17 Push and Pop Javascript Array Methods

In this lesson, we are going to learn more about arrays in JavaScript, and we will learn some built-in array methods.
So here we are going to discuss two paired methods in which we learn how we can add and remove items from the end of an array list.

Lesson 18 Shift & Unshift, indexOf and Slice Array Method in Javascript

In this lesson, we are going to discuss more about array method in Javascript, and in this lesson, we will learn about another paired method Shift and Unshift, and learn how we can remove and add items at the beginning of Array list. We are also going to discuss sort() method there.
So we will also learn how we can arrange array items in alphabetical order.

Lesson 19 IndexOf, Slice Array Method in Javascript

In this lesson, we are going to discuss two more methods of Array, indexOf() method and slice() method, and we are going to discuss how we can find if the particular item exists in the array list or not, and we will also learn how we can copy particular items from arrays and store in some other array.

Lesson 20 Objects in JavaScript

So in the last few lessons, we have been talking about arrays which are a part of the data structure. In this lesson, we will discuss Objects in JavaScript which is also a part of data structure and we will also discuss what objects are and how we can use objects in our program.

Lesson 21 Difference in Arrays And Objects in Javascript

In this lesson we are going to compare arrays and objects in JavaScript, we are going to discuss how arrays are different from the object. We will discuss the syntax of both data structure and we will learn how we can add, retrieve data from object and array.
