Defining Interface


You can think of Typescript interface as "data structure" that describes the properties of an object.

Suppose you want a Stock object that takes in name & quantity thereafter add to an array for some processing.


Copy the code below to run on an online typescript compiler.



Explaination:

Here we created an Stock interface that holds the properties of name and qty. Loaded it with some default constant data thereafter added two new data to the array & added filtering functions.
