you should use usestate
as said in the following way:
const [info, setinfo] = usestate({name: '' })
if (info.name === '') {
setinfo({...info, name = 'empty'});
}
this will set info with only the change of the name property

a hook is something that starts with use
like usestate
. setstate
is not a hook - it's a setter/updater. it can be used inside of a conditional statement. if it's done properly there shouldn't be any infinite loops.
score:0
in react functional components, usestate hook is used as an alternate to state in class components. the correct way to use the usestate hook is
const [ variable, setvariable ] = react.usestate( //default value );
the default value can be null, " string ", { object } , true / false, or 0, 1, 2 .......
and just like this.setstate() in class components, you set the state with the
setvariable( newvalue );
never ever try to change the state variables like you change the normal variables. they are immutable for one render and hence cause re-render when called setstate.
and for the infinite loop, please copy paste your component
