Unexpected reserved word 'yield' in redux saga reactjs

Question

I started with reactredux saga and this is my code for currentUserSaga.js.
currentUserSaga.js

import {delay} from 'redux-saga'
export function* currentUserSaga () {
    while(true){
        yield delay(1000);
        console.info("User Saga loop");
    }
}

While compiling I am getting following error.

SyntaxError: /home/Sakthy/Desktop/React Saga/redux-saga-cart/src/sagas/currentUserSaga.js: Unexpected reserved word 'yield' (4:8) 2 | export function currentUserSaga () { 3 |
while(true){> 4 | yield delay(1000); | ^ 5 |
console.info("User Saga loop"); 6 | } 7 | }

Please guide me I am following a tutorial but I think it's due to wrong use case of yield keyword.

Answer 1

we expect generating functions to generate a value, and remember that the yield must return a value at each iterate, not a function that does not return anything.
