To update the attribute value of an object using the map function in JavaScript, we return the updated object.
For instance, we write
const editSchoolName = (schools, oldName, name) =>
schools.map((item) => {
if (item.name === oldName) {
return { ...item, name };
} else {
return item;
}
});
to define the editSchooName
function that returns a new version of the schools
array that has entries mapped from schools
with the objects updated if they have name
property equal to oldName
.
