I am learning typescript from past few days and came across a data type called Symbol. But I really did not understand the applications of it.

When I can assign a string to a variable like below:

let str="mystring";

Why should I use -

 let str=Symbol("mystring");

What is the advantage of using Symbol in typescript? What is the need of this data type and when to use it? Can someone explain please.

    The docs look pretty self explanatory to me https://www.typescriptlang.org/docs/handbook/symbols.html – Kurt Hamilton Feb 18 '20 at 10:59

    yes I went through this document but they only guide about how to use it. But my question is when to use it. – gangothri urs Feb 18 '20 at 11:02
