 Okay, let's talk in this tutorial about functions with default parameter values in Javascript ECMAScript version 6. Before ECMAScript 6, it was very difficult to create a function with default parameter values in Javascript, but now in ECMAScript, it's very easy. I'll show you that by using a simple example. I'm going to make add function and I'm going to provide three arguments for our function and simply I'm going to return the sum of these three numbers, okay. And in ECMAScript, it is very easy to use default values for our parameters. For example, I'm going to say that the value for the second parameter is going to be 10 and the default value for the third parameter is going to be returned by my value function. Now I want to declare my value function. It's going to be a simple function. It's going just to return, for example, number 5 and then simply I just want to call this add function by providing just the first argument because the second argument by default is going to be number 10 and the third argument by default is going to be the returning value of my value function, which in this case is going to be number 5. Okay, let's run this code and as you can see we have as the result of this function number 115 because number 1 is going to have value 100, number 2 by default is going to have value 10 and number 3 by default is going to have value 5. That's all in this lesson. Don't forget to subscribe to my channel. See you in the next tutorial.
