Welcome to part-3 of the series. You can find part-2 here.

We will start with loops in this part.

Loops

The first loop which will look is the traditional for loop, which is their in all languages.

Let’s look into the for loop below -

for(let i=0; i <= 10; i++){
  console.log(`Loop Number - ${i}`);
}

Now, the flow of the loop is like for the first time let i=0 will run. After that i <= 10 will run. Now it will be true because 0 is less than or equal to 10. And, so the output of Loop Number- 0 will be printed.

Next, time the i++ will run, which is equivalent to i = i + 1. So, the i is now 1. Again the condition i <= 10 will run. Now it will be true because 1 is less than or equal to 10. And, so the output of Loop Number- 1 will be printed.

The loop will run till i is 10 and will print the outputs. Now, when i will be 11 after the increment and the condition i <= 10 will run. It will be false because 10 is less then equal to 10 will be false. So, the loop will end and come out.
