how to use the tostring function from the rxjs library in javascript

The toString() function in the RxJS library is used to convert an object to a string. The syntax for using this function is:

index.tsx
observableObj.toString();
26 chars
2 lines

Here, observableObj is the object that needs to be converted to a string.

For example, consider the following code:

index.tsx
const { of } = require('rxjs');
const { map } = require('rxjs/operators');

const observable = of(1, 2, 3).pipe(map(x => x * 2));

console.log(observable.toString());
167 chars
7 lines

In this code, we have created an observable that emits the values 1, 2, and 3 and then applies the map() operator to double these values. Then we have used the toString() function to convert this observable to a string and log it to the console.

The output of the above code will be:

index.tsx
Observable { _subscribe: [Function] }
38 chars
2 lines

This is the string representation of the observable object.
