Repeated calls to the function will return the value from the first invocation.
Signature
function once<F extends () => any>(func: F): F;
function once<F extends (...args: any[]) => void>(func: F): F;
Parameters
func(F extends (() => any) | ((...args: any[]) => void)): The function to restrict.
Returns
(F): A new function that invokes func once and caches the result.
Examples
const initialize = once(() => {
console.log('Initialized!');
return true;
});
initialize(); // Logs: 'Initialized!' and returns true
initialize(); // Returns true without logging
