 Ok, let's talk in this tutorial how to check whether a string contains a substring in JavaScript or ECMAScript 6. I'm going to create a string, let's call it myString, and I will put some text inside it, for example, Berlin, Germany, and then I want to search if this string contains a substring. For example, I will search for substring lin inside this string. In order to do that, we're going to use new method presented in ECMAScript 6. It includes method, I want to print result to the console, so I will say console log and inside our console I want to use my string and call upon it includes method and inside it as an argument, I'm going to provide a substring which I want to search in this string, I want to search for substring lin. So I will put here substring lin, ok, now I'm going to press enter and as you can see the returning value of calling includes method upon our string is true because this substring is contained inside this string. That's all in this lesson, don't forget to subscribe to my channel, see you in the next tutorial, bye.
