you can use a usestate
variable and set result to it after calling checkchanges()
const [valid, setvalid] = usestate(false);
const checkchanges = () => {
// takes email value from state
// checks if it's valid
return setvalid(result) // true or false after validating
}
return (<button onclick={() => savechanges()} disabled={!valid}>click me</button>) {/* disable if not valid*/}
