In this course the following code is used.
const person = { name: 'Andrew Chalkley', role: 'JavaScript Teacher' }
function logTeacher(teacher) {
console.log(${teacher.name} - ${teacher.role}
); }
logTeacher(person);
Q: my question is this. from what i understand this function ' teacher' is using properties from the object literal person. in the line console.log(${teacher.name} - ${teacher.role}
); }
i would have tought that the code should be:
console.log(${person.name} - ${peron.role}
); } . both code options give the same results.
why does ${teacher.name} and ${person.name} give the same results?

and ${person.name}
give the same result in this case because logTeacher
is only called once, with the argument person
, in the line logTeacher(person);
.
If you change the argument passed into the function, the output will change.
const person = { name: 'Andrew Chalkley', role: 'JavaScript Teacher' };
logTeacher(person); // outputs 'Andrew Chalkley - JavaScript Teacher'
const person1 = { name: 'Max van den Berge', role: 'JavaScript Student' };
logTeacher(person1); // outputs 'Max van den Berge - JavaScript Student'
If you change the logTeacher
function to
function logTeacher(teacher) {
console.log(`${person.name} - ${person.role}`);
}
then the teacher
parameter will be ignored in the output:
const person = { name: 'Andrew Chalkley', role: 'JavaScript Teacher' };
logTeacher(person); // outputs 'Andrew Chalkley - JavaScript Teacher'
const person1 = { name: 'Max van den Berge', role: 'JavaScript Student' };
logTeacher(person1); // outputs 'Andrew Chalkley - JavaScript Teacher'

6,506 Pointsthx jb30 for this explanation.
Is this thought process correct:
The function has an argument ( teacher ) , but the output logTeacher ( the name of the function ) refers to the object literal person1. In this object literal there is a value of
