Answer: A


NEW QUESTION # 35
Refer to the code below:
class Student {
constructor(name) {
this._name = name;
}
displayGrade() {
console.log(`${this._name} got 70% on test.`);
}
}
class GraduateStudent extends Student {
constructor(name) {
super(name);
this._name = "Graduate Student " + name;
}
displayGrade() {
console.log(`${this._name} got 100% on test.`);
}
}
let student = new GraduateStudent("Jane");
student.displayGrade();
What is the console output?

Answer: A

Explanation:
The correct answer is C, after correcting the option text to match the actual code.
The object is created here:
let student = new GraduateStudent("Jane");
Because GraduateStudent extends Student, its constructor runs:
constructor(name) {
super(name);
this._name = "Graduate Student " + name;
}
The call to:
super(name);
runs the parent Student constructor first and temporarily sets:
this._name = "Jane";
Then this line in the child constructor overwrites that value:
this._name = "Graduate Student " + name;
So the final value of this._name becomes:
"Graduate Student Jane"
Next, this line executes:
student.displayGrade();
Since student is an instance of GraduateStudent, JavaScript uses the overridden displayGrade() method from GraduateStudent, not the parent method from Student.
The executed method is:
displayGrade() {
console.log(`${this._name} got 100% on test.`);
}
Therefore, the console output is:
Graduate Student Jane got 100% on test.
Important correction: the original option C said something like "Better student Jackie got 100% on test.", but the actual code uses "Graduate Student " and the name "Jane". The verified corrected answer remains C.


NEW QUESTION # 36
Refer to the code below:
const searchText = 'Yay! Salesforce is amazing!';
let result1 = searchText.search(/sales/i);
let result2 = searchText.search(/sales/);
console.log(result1);
console.log(result2);
After running this code, which result is displayed on the console?

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract JavaScript Knowledge:
String: "Yay! Salesforce is amazing!"
Index positions:
'Y' at 0, 'a' at 1, 'y' at 2, '!' at 3, space at 4, 'S' at 5, 'a' at 6, 'l' at 7, 'e' at 8, 's' at 9, etc.
Substring "Sales" starts at index 5.
String.prototype.search with a regex returns the index of the first match or -1 if there is no match.
searchText.search(/sales/i);
/sales/i is case-insensitive because of the i flag.
It matches "Sales" beginning at index 5.
So result1 is 5.
searchText.search(/sales/);
/sales/ is case-sensitive.
It requires lowercase "sales".
The text has "Sales" with uppercase S, so this does not match.
search returns -1 when there is no match.
So result2 is -1.
Console output:
First log: 5
Second log: -1
Option D matches this.
Concepts: regex search, case sensitivity vs i flag, String.prototype.search return values.

NEW QUESTION # 37
Why does second have access to variable a?

Answer: D

Explanation:
The answer is B because JavaScript uses lexical scope.
When a function is created inside another function, the inner function can access variables from the outer function where it was defined.
For example:
function first() {
let a = 10;
function second() {
console.log(a);
}
second();
}
Here, a belongs to the outer function first(). The inner function second() can access it because JavaScript looks for variables through the scope chain.
The lookup works like this:
1. Look inside second()
2. If not found, look inside first()
3. If not found, look in the global scope
Since a is found in the outer function's scope, second() can use it.
This is also the basis of a closure. A closure allows an inner function to remember and access variables from its outer lexical environment.
Why the other options are incorrect:
A is not the best answer because a is not declared inside second() itself.
C is incorrect because the prototype chain is used for object property lookup, not local variable scope lookup.
D is incorrect because hoisting explains how declarations are moved during compilation, but it does not explain why an inner function can access an outer function's variable.
Therefore, the verified answer is B.
