Accepted answer
you can move react.createcontext
outside of the component's body, pass a value for the context at the provider and use react.usecontext
for accessing the context's value.
const appcontext = react.createcontext('codeinabottle');
export default function app() {
return (
<div>
<appcontext.provider value="somevalue">
<router>
<header />
<switch>
<route exact path="/">
<home />
</route>
</switch>
<footer />
</router>
</appcontext.provider>
</div>
);
}
export default function header() {
const somevaluefromthecontext = react.usecontext(appcontext);
console.log(somevaluefromthecontext); // 'somevalue'
return (
<header>
<link to="/">{app}</link>
</header>
);
}
