Trying react new simpleCacheProvider module

test.js

const test = async () => {
    const { createCache, createResource } = require('./cacheProvider');

    function loadUpperCase(text) {
        console.log('CALLED!');
        return Promise.resolve(text.toUpperCase());
    }

    function loadUpperCase2(text) {
        console.log('CALLED 2!');
        return Promise.resolve(text.toLowerCase());
    }

    const UpperCase = createResource(loadUpperCase);
    const UpperCase2 = createResource(loadUpperCase2)
    const cache = createCache();

    let suspender;
    try {
        UpperCase.read(cache, 'cok');
    } catch (v) {
        suspender = v;
    }

    await suspender;

    let suspender2;
    try {
        UpperCase2.read(cache, 'COK');
    } catch (v) {
        suspender2 = v;
    }

    await suspender2;

    const result = UpperCase2.read(cache, 'COK');
    const result2 = UpperCase.read(cache, 'cok');
    const result3 = UpperCase.read(cache, 'cok');
    const result4 = UpperCase2.read(cache, 'COK');
    console.log('RESULT:1', result);
    console.log('RESULT:2', result2);
    console.log('RESULT:3', result3);
    console.log('RESULT:4', result4);
};
