How to call FETCH once?

Question

JavaScript

Hello.
There is a request in which the data comes.
How and where is it better to write them down so that they can be used in other functions?

function func() {
    fetch('bla-bla-bla')
        .then(data => data.json())
        .then(data => data)
}

I want to use data in other functions.
Sorry for stupid question :)

Answer 1

Declare a variable outside the function and put the result of the fetch in it.

Answer 2

const func = (() => {
    const url = 'bla-bla-bla';
    let result;

    return async () => {
        if (typeof result == 'undefined') {
            result = await (() => {
                return fetch(url).then(response => response.json());
            })();
        }

        return result;
    };
})();
