There are 21 kinds of lessons in all.
Please take your desired lesson.
In this lesson, we are going to introduce null type and undefined type and then we are going to differentiate these both types with examples.
We are also going to give a quick overview about Boolean data type.
We are also going to learn how you can recall variable and how you can change its value.
We will also learn comparison operators.
In this lesson, we will learn about the logical operators, AND, OR and NOT and we are going to see that how do we change a simple Boolean statement into the complex statements that have multiple components.
In this part, we will cover one of the most important concepts of every programming languages which is conditionals.
In this lesson, we will also learn about the conditional statement like if, else and else if, these statements help us to add logic to our programming.
So in this lesson, we are going to learn for loop and its purpose.
At the end of this lesson, you will know how valid for loop can be written.
We will also compare and contrast while loop and for loop.
The objectives of this lesson are:
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.
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.
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.
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.
We are also going to discuss sort() method there.
So we will also learn how we can arrange array items in alphabetical order.
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.
