I am write my code like this:
const mika = pera.filter(id=>{
return (id.id=== 2);
});
const mika1 = mika.map((primer,i)=>{
return(
{primer.id} {primer.title}
);
});
but I can't format this data in return section of component divide, accept if I do that in constant mika1. How must write code for another solution?
