How to use Tuples in TypeScript Examples

So what are tuples? And why do we even bother to invent something like this? The reason behind that is arrays are used to group the objects of similar data types. In such case adding string and numbers would require you to have different collection instead of arrays. So in such case the tuples can be used as well.

Here's the simple syntax of the tuple.

var tuple_name = [value1,value2,value3,…value n]

You have to specify the var and then followed by the tuple name and then keep on adding the mixed data type values in square bracket. You can check out the sample below for code that works as a tuple.

var mytuple =  [10,"devnami"];

So now you get the idea what are tuples and how they work. You should definitely check the example live on above video.

So that's simple demo for you to check out. I recommend checking out Learning Typescript book. Let me know if you like the video.
