ReactJs: Prevent multiple times button press

Question

In my React component I have a button meant to send some data over AJAX when clicked. I need to happen only the first time, i.e. to disable the button after it\'s first use.

const once = (f, g) => {
    let done = false;
    return (...args) => {
        if (!done) {
            done = true;
            f(...args);
        } else {
            g(...args);
        }
    };
};

const exampleMethod = () => console.log("exampleMethod executed for the first time");
const errorMethod = () => console.log("exampleMethod can be executed only once")

let onlyOnce = once(exampleMethod, errorMethod);
onlyOnce();
onlyOnce();

output

exampleMethod executed for the first time
exampleMethod can be executed only once
