Create benefactor phone number

hello world welcome to another video so today what we are going to solve is something called as creating a phone number again as you can notice this is a rank six one and it is something that has been given to me in the rank up series you can change this to whatever you want so i'm just going to stay in the rank up and then i'm going to train with that so create a phone number what exactly is this so you need to write a function that accepts an array of 10 integers between 0 and 9 okay that returns a string of those numbers in the form of a phone number okay so you get something like this and then you return a string okay the returned format must be correct in order to complete this challenge okay don't forget the spaces space after the closing parentheses all right so the first three numbers should be inside the parentheses okay let's just say this [Music] array of 10 integers is our input right and then what we need to do is travel through the array right after you travel through the array you add first three integers in the resulting string right and then after you do that you again travel through the array add next three integers and then hyphen right so first one you need to do is add this parentheses then you add that then you add the closing parenthesis with a space right and then you travel through you add the next three integers and then that and then add the rest right so we can use the splice method right so let's just see what exactly is this splice method see all right dot splice so basically you say splice methods adds or removes item from an array and then this method changes the original array right that is what we want so what we need to do is index so starting from this how many elements do you want to remember remove right so we have an array now let's just say let phone number equal to us wait it returns what does it return returns the remote items right okay so let's just say phone number is equal to this numbers dot splice starting from zero i need three right so i'm just going to console log this phone number to see what exactly is happening console.log phone number right let's just test it out so we have an array so what we need to do is let's let's do this we are going to call this as a string and then initially right initially it's going to have the opening braces right so later once we slice the first three strings we need phone number equal to so plus equal to four number of number of slices blah blah blah dot join at nothing right let's just test this out i need one two three perfect so...
