Hi, need me little help with use context. Exactly I wish use data from function noviPodaci() { fetch("http://localhost:3000/posts.json") .then(response => { return response.json(); }) .then(json => { console.log("parsed json iz funkcije noviPodaci", json); alert([json.name, json.id, json.email]); }) .catch(function(ex) { console.log("parsing failed", ex); }); } to import React from "react"; import "whatwg-fetch"; export const CTX = React.createContext(); export default function Store(props) { const statHooks = React.useState({ color: colors, naziv: ime, new: "data of function }); return ( <CTX.Provider value={statHooks}> <div>{props.children}</div> </CTX.Provider> ); } How do that? You can see all code at https://codesandbox.io/s/naughty-hypatia-swsqm Thanks Mr.Miodrag
