Composing Sagas

Use call to call another saga:

const saga = createSaga(async function() {
    return 2;
});

const main = createSaga(async function() {
    const result = await this.call(saga);
    console.log(result); // 2
});

Use callFn to call another function:

const fn = () => 2;

const main = createSaga(async function() {
    const result = this.callFn(fn);
    console.log(result); // 2
});

Use callPromise to call another promise:

const promise = Promise.resolve(2);

const main = createSaga(async function() {
    const result = await this.callPromise(promise);
    console.log(result); // 2
});
