react make SetState synchrone
class MyComponent extends React.Component {
function setStateSynchronous(stateUpdate) {
return new Promise(resolve => {
this.setState(stateUpdate, () => resolve());
});
}
async function foo() {
// state.count has value of 0
await setStateSynchronous(state => ({count: state.count+1}));
// execution will only resume here once state has been applied
console.log(this.state.count); // output will be 1
}
}
