 Hi again, in this lesson we are going to write our first program in javascript programming language. We want to show alert with text hello world in our html page on our web browser. First what we need to do is to open our new html page and put some default text that every html page needs to have and inside our body we will put script tags and inside those script tags we will write our javascript code. We want to alert a message on our web browser, so we will say in this message hello world and after our statement we will put semicolon, ok now let's save our program and let's open it in a web browser, I will use live preview and as you can see we have alert pop-up box with text hello world in our page on our browser, I will click ok, so that's all in this lesson we've successfully written our first program in javascript. Thanks for watching, happy coding.
