NEW QUESTION # 144
What are two unique features of fat-arrow functions compared to normal function definitions?

Answer: B,C

Explanation:
Arrow functions have two defining characteristics:
Implicit return when written as a single expression:
const fn = () => 5; // returns 5 automatically
This is unique to arrow functions → A is correct.
Lexical this binding:
Arrow functions do not create their own this.
Instead, they use the this value from the surrounding scope → B is correct.
Incorrect options:
C is false: There is no special argument called parentThis.
D is the opposite of arrow function behavior:
Normal functions create their own this; arrow functions do not.
JavaScript Knowledge Reference (text-only)
Arrow functions have lexical this binding.
Arrow functions support implicit return for single expressions.


NEW QUESTION # 145
Refer to the code below:

Considering that JavaScript is single-threaded, what is the output of line 08 after the code executes?

Answer: B


NEW QUESTION # 146
Corrected code:
let obj = {
foo: 1,
bar: 2
};
let output = [];
for (let something in obj) {
output.push(something);
}
console.log(output);
What is the output of line 11?

Answer: C

Explanation:
The verified answer is C.
This object has two properties:
let obj = {
foo: 1,
bar: 2
};
The property names are:
foo
bar
The property values are:
1
2
The loop used here is a for...in loop:
for (let something in obj) {
output.push(something);
}
A for...in loop iterates over the property keys of an object, not the property values.
So during the first iteration:
something === "foo"
The code pushes "foo" into the array.
During the second iteration:
something === "bar"
The code pushes "bar" into the array.
The final value of output is:
["foo", "bar"]
That is why:
console.log(output);
prints:
["foo", "bar"]
Option B would be correct only if the code pushed the values, for example:
output.push(obj[something]);
Option D would require building formatted strings manually, such as:
output.push(`${something}:${obj[something]}`);
But the given code only pushes the property names.
Therefore, the verified answer is C.


NEW QUESTION # 147
A developer has the function, shown below, that is called when a page loads.

Answer: A
