i have a function like below to be called on button click using react and typescript.
function Parent () {
const [isOpen, setIsOpen] = React.useState(false);
const handleClick = () => {
setIsOpen(open => !open);
}
return (
<button onClick={handleClick}>click me </button>
);
}
How can i rewrite handleClick
method using React.usecallback
method?
could someone help me with this. thanks.
We just wrap the functional and add our isOpen to the list of dependent variables, since it will change every click time.
const handleClick = React.useCallback(() => {
setIsOpen(open => !open);
}, [isOpen]);
