 Hi, let's talk about arrays in TypeScript. TypeScript like JavaScript allows us to work with arrays. We have two ways to write an array in TypeScript. Let's write it on the first way. For example, let's say variable array 1, which will be the array of numbers. And let's populate our array with few values, 1, 2, 3, 4 and 5. So if you want to define your array, you need to put your variable name, then you need to put type of your variable. After that type, you need to put brackets. These brackets will signify that our array will have these type elements. And then you can populate your array with few elements on or leave it empty, like this with empty brackets. Then we have the second way to define our array. We can define it by using generic array type. So we're going to use this array type and let's make our second array variable. It will have array type and we want to say that our array is going to be array of numbers. Okay, let's also populate it with few numbers, 1, 2, 3, 4 and 5. So these two versions are the same. They will generate the same JavaScript output. Of course, if you want, you can define any other type for your array. For example, you can use strings. You can define strings array, let's call it array 3 and let's define string. Let's make our code look little better. Okay, and let's populate our string with, I don't know, maybe few letters. For example, letters A, B and C and similarly, you can define your string array with generic array type, but in this situation, in our example, we're going to put string inside of arrays, generic says an argument and again, okay, let's make it to be an empty string or okay, let's define few values. Then of course, you can create an empty array. You can create array, for example, that has any type. For example, let's create an empty array, which will have any type. And you can create it by using new keyword and let's create new empty array object with new array. This syntax is very similar with Java or C sharp syntax. You are familiar with those programming languages, learning how to work with type scripts and how to define new objects or empty arrays will be very easy for you. That's all in this lesson. Thanks for watching.
